jQuery Cloning and incrementing input, textarea, that has name, id and for

I'm still very new to jQuery, and would need help to how to increment 3 elements in this code.
name, id & for.
The name consist of products[0]category, id consist of checkbox[0], for consist of checkbox[0] which is for labels on the checkbox that id use.
I've tried searching for examples. But all them haven't found any good results that i could learn from unfortunately. So in the codes below, they're not there to increase increment as i have totally no idea what else i can do to increase increment numbering.
$(document).ready(function() {
let $append = $('#append');
// append location's data listing
$append.on('change', '.location', function(){
var value = $(this).val();
$('.location_id').val($('#locations [value="'+value+'"]').data('locationid'));
$('.loc_desc').val($('#locations [value="'+value+'"]').data('locdesc'));
});
// enable checkbox for serialnumbers
$append.on('change','.enable-serial', function(){
let $item = $(this).closest('.product-item');
let $checkbox = $item.find('.enable');
$checkbox.prop('disabled', !this.checked);
});
// ctrl for key in checkbox
$append.on('click', '.keyin-ctrl', function() {
let $container = $(this).closest('.product-item');
let $serial = $container.find('.serial');
$container.find('.display').val(function(i, v) {
return v + $serial.val() + ';\n';
});
$serial.val('').focus();
});
// ctrl for del textarea
$append.on('click', '.undo-ctrl', function() {
let $container = $(this).closest('.product-item');
$container.find('.display').val('');
});
// clone product, increment products[x]var
$('#add_product').on('click', function() {
var itemNo = $('.product-item').length + 1;
var index = $('.product-item').length;
var regex = /^(.+?)(\d+)$/i;
let $product = $append.find('.product-item.template')
.clone()
.show()
.removeClass('template')
.insertAfter('.product-item:last');;
$product.find('span').text('#' + itemNo);
$product.find(':checkbox').prop('checked', false);
$product.find('.enable').prop('disabled', true);
$product.find('input, textarea').val('');
$('#append').append($product);
});
// delete product, but remain original template intact
$('#delete_product').on('click', function(){
var itemNo = $('.product-item').length + 1;
let $product = $append.find('.product-item:last:not(".template")');
$product.remove();
});
});

So how do I actually achieve this to add increment to the NAME, ID and FOR my clones?
From the original template of products[0]variable to products[1]variable, checkbox[0] to checkbox[1]

If you want to increment either an ID, class, etc. you can't use .clone(), like the documentation warns:
Using .clone() has the side-effect of producing elements with
duplicate id attributes, which are supposed to be unique. Where
possible, it is recommended to avoid cloning elements with this
attribute or using class attributes as identifiers instead.
You'll have to do it "manually", following a very simple example below:
$( "#addrow" ).click(function() {
var count = $("#product").children().length;
$("#product").append("<input id='field[" + count + "]' type='text'>");
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="product">
</div>
<input id="addrow" type="button" value="Add field">

Removing appended html code

I currently ran into a problem that i cannot remove the appended html with jQuery.
What works now is i can append the html that i want and it looks nice, but removing does not work. It works only on reload the first loaded html the others that i append are not working - I don't know why.
Here is my code for appending the html:
$("#adWasteStream").click(function(){
var newTxt = $('<div class="row-waste-container width-100"><div class="row"><div class="col-md-9"><p>Stream 1</p></div><div class="col-md-3"><button class="btn btn-add-waste deleteWasteStream"><i class="fa fa-minus-circle o-btn-add" aria-hidden="true"></i>Remove Waste Stream</button></div><div class="form-group col-md-7"><label for="business-mng-name" class="control-label">Waste Stream</label><input type="text" class="form-control form-input-field" name="business-mng-name" value="" required="" placeholder="Co-mingled recycling"><span class="help-block"></span></div></div><div class="row width-100"><div class="form-group col-md-4"><label for="business-mng-name" class="control-label">Volume (m <sup>3</sup>)</label><input type="text" class="form-control form-input-field" name="business-mng-name" value="" required="" placeholder="50"><span class="help-block"></span></div><div class="form-group col-md-4"><label for="business-mng-name" class="control-label">Weight (t)</label><input type="text" class="form-control form-input-field" name="business-mng-name" value="" required="" placeholder="20"><span class="help-block"></span></div><div class="form-group col-md-4"><label for="business-mng-name" class="control-label">Cost ($)</label><input type="text" class="form-control form-input-field" name="business-mng-name" value="" required="" placeholder="400"><span class="help-block"></span></div></div></div>');
$(".row-cont-main").append(newTxt);
});
My code for removing:
$(".deleteWasteStream").click(function(){
var curRow = $(this).parents('div.row-waste-container');
curRow.remove();
});
I don't need to use Id's as they need to be unique all elements (for back-end purposes).
The structure of the html looks like this:
<div class="row-waste-container width-100">
<div class="row">
<div class="col-md-9">
<p>Stream 1</p>
</div>
<div class="col-md-3">
<button class="btn btn-add-waste deleteWasteStream"><i class="fa fa-minus-circle o-btn-add" aria-hidden="true"></i>Remove Waste Stream</button>
</div>
<div class="form-group col-md-7">
<label for="business-mng-name" class="control-label">Waste Stream</label>
<input type="text" class="form-control form-input-field" name="business-mng-name" value="" required="" placeholder="Co-mingled recycling">
<span class="help-block"></span>
</div>
</div><!-- end row -->
<div class="row width-100">
<div class="form-group col-md-4">
<label for="business-mng-name" class="control-label">Volume (m <sup>3</sup>)</label>
<input type="text" class="form-control form-input-field" name="business-mng-name" value="" required="" placeholder="50">
<span class="help-block"></span>
</div>
<div class="form-group col-md-4">
<label for="business-mng-name" class="control-label">Weight (t)</label>
<input type="text" class="form-control form-input-field" name="business-mng-name" value="" required="" placeholder="20">
<span class="help-block"></span>
</div>
<div class="form-group col-md-4">
<label for="business-mng-name" class="control-label">Cost ($)</label>
<input type="text" class="form-control form-input-field" name="business-mng-name" value="" required="" placeholder="400">
<span class="help-block"></span>
</div>
</div><!-- end row -->
</div><!-- end row-waste container -->

You need to change your click event handler to handle also dynamically appended html.
Update your remove click handler with the code below
$("body").on('click' , '.deleteWasteStream' , function(){
var curRow = $(this).parents('div.row-waste-container');
curRow.remove();
});

You cant use .click() on dynamic objects/html. You can use .on()
$("body").on('click', '.deleteWasteStream', function( event ) {
var curRow = $(this).parents('div.row-waste-container');
curRow.remove();
});
Documentation: http://api.jquery.com/on/

Since the elements were created dynamically, they are not registered in DOM like pre-rendered elements (those rendered when your webpage is loaded in the browser). The best solution is binding the dynamically created element to the prerendered ones using the on event binder
$('.row-cont-main').on('click','.deleteWasteStream',function(){
var curRow = $(this).parents('div.row-waste-container');
curRow.remove();
});

How to add dynamic data attribute value to a button and a div generated by repeater.js

I am using repeater.js to repeat a div with some input fields and button, but the problem is that i want to give each and every div a unique id so that i can extract data from all the fields of that particular div input elements.
this is the HTML Code:
<div class="form-group mt-repeater">
<a href="javascript:;" data-repeater-create class="btn btn-circle purple mt-repeater-add">
<i class="fa fa-edit"></i> Repeat Field
</a>
<div data-repeater-list="group-b">
<div data-repeater-item class="mt-repeater-item">
<div class="mt-repeater-cell">
<div class="row">
<div class="col-md-2">
<div class="form-group">
<div class="input-group">
<input type="text" id="dosage_form" class="form-control typeahead-findings circle-input" placeholder="Dosage Form">
<label for="dosage_form">e.g. Tablet / Syrup / Capsule etc.</label>
</div>
</div>
</div>
<div class="col-md-2">
<div class="form-group">
<div class="input-group">
<input type="text" id="brand_name" class="form-control typeahead-findings circle-input" placeholder="Brand / Generic Name">
<label for="brand_name">e.g. Dytor</label>
</div>
</div>
</div>
<div class="col-md-2">
<div class="form-group">
<input class="form-control circle-input" id="contents" type="text" placeholder="Contents" />
<span class="help-block"> e.g Paracetamol </span>
</div>
</div>
<div class="col-md-2">
<div class="form-group">
<div class="input-group">
<input type="text" id="dose" class="form-control typeahead-findings circle-input" placeholder="Dose">
<label for="dose">e.g. 20 mg / 20 ml</label>
</div>
</div>
</div>
<div class="col-md-2">
<div class="form-group">
<input class="form-control circle-input" id="dose_regimen" type="text" placeholder="Dose Regimen" />
<span class="help-block"> e.g 1-1-1-1 </span>
</div>
</div>
<div class="col-md-2">
<div class="form-group">
<div class="input-group">
<input type="text" id="therapy_duration" class="form-control typeahead-findings circle-input" placeholder="Therapy Duration">

</div>
<div class="col-md-1 col-sm-6 col-xs-6">
<i class="fa fa-plus"></i>
</div>
<div class="col-md-1 col-sm-6 col-xs-6">
<i class="fa fa-minus"></i>
</div>
</div>
</div>
</div>
every time i click on the add repater button this div gets replicated but what i also want is that the new div generated should have a unique div id also the curresponding elemnts inside it should have a class or id starting with that id so that data extraction can be easy for that particular div
I was using this Jquery code:
$(".addData").on('click' ,function()
{
alert("hi");
});
This is the repeater i am using: https://pastebin.com/n7g7tdTH
but this code only runs for the very first div on the later generated dynamic divs it doesn't run. I also tried editing the repeater.js but no success because its all dynamic and i am not able to understand where i should edit that code to add a dynamic data-counter value for the div and the corresponding elements.
Can anyone help with this logic?

Another option, to retrieve field values would be to rename all input field id with name (example below) and use repeater.js repeaterVal() to get all the field values .
$(".mt-repeater").repeater();
$("#getVal").click(function () {
$('.mt-repeater').repeaterVal()["group-b"].map(function(fields){
//fields contain the collection of input fields per row
console.log(fields["dosage_form"]);
console.log(fields["brand_name"]);
//....
})
})

<button id="getVal">Get Value</button>

For the first problem..
but this code only runs for the very first div on the later generated
dynamic divs it doesn't run
You can convert your jquery events into delegated events.. These allow you to catch events on DOM elements based on a selector, so when newer DOM elements are added these are caught too.
So -> $(".addData").on('click' ,function()
As a delegated event becomes -> $(document.body).on("click",".addData" ,function()
The second problem.
but how to get the values from the input field that are present near that button
This can be achieved by traversing up the DOM tree to a parent that surrounds the elements you want,. eg. .row or maybe mt-repeater-cell, as long as it's a DOM element that contains the elements you want to find. Here you can use jquery's closest selector, that will traverse up the tree until it finds the element your after.
So -> $(this).closest('.row').find('#dose_regimen').val()
The above will traverse up the DOM tree until it finds a .row class, we then find element with id dose_regimen etc,.. #dose_regimen and then finally get it's value with .val()

Form not validating required fields with BootStrap

I have a form that submits with empty required fields.
I'm using Twitter BootStrap with it.
I posted this example in jsFiddle.
Maybe is just an tag issue from BootStrap, but i'm really not seeing what is wrong.

3 things:
That is not how you use required.
You need to wrap your jQuery code in .ready().
Move the <button> element inside the <form> and make it type="submit".
Updated Code:
$(document).ready(function(){
$(".action").click(()=>{
$(".ajaxForm").submit();
});
$(".ajaxForm").submit(()=>false);
});
<link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">

<div class="container col-sm-6 col-xs-12">
<div class="form-group input-group">
<span class="input-group-addon">

</span>
<input type="text" class="form-control cpf" required />
</div>
</div>
<button type="submit" class="action btn btn-success">Teste</button>
</form>
Updated jsFiddle

Thanks for the answers.
Since I have a button (div, actually) outside the form that will trigger the submit, I found my way by (quick fix) triggering a click on a hidden submit button.
The HTML:
<link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<form class="ajaxForm">
<div class="container col-sm-6 col-xs-12">
<div class="form-group input-group"> <span class="input-group-addon">
Nome
</span>
<input type="text" class="form-control nome" required />
</div>
</div>
<div class="container col-sm-6 col-xs-12">
<div class="form-group input-group"> <span class="input-group-addon">
CPF
</span>
<input type="text" class="form-control cpf" required />
</div>
</div>
<input type="submit" style="display:none" /> <!-- The hidden button -->
</form>
<button class="action btn btn-success">Teste</button>
The JavaScript:
$(".action").click(() = > {
$(".ajaxForm input[type='submit']").click();
});
$(".ajaxForm").submit(() = > false);
So, this quick fix will work, for now. Here is the jsFiddle updated.

Adding ng-autocomplete to input tag when dynamically creating the input tag via Javascript

"Sorry for my English as it is not my native language"
On to the problem. I have a trouble with ng-autocomplete when I dynamically create form fields.
The ng-autocomplete works fine when I create an input tag in the index file but when I try to add more tags via the javascript function the ng-autocomplete does not work in the new input tags created..
As you see in the picture the two input fields "Travel from" and "Travel to" have ng-autocomplete but the input field "travel via" which is created by the javascript function does not have ng-autocomplete..
The question is how can I add a working ng-autocomplete for every created input field via the function?
Down below is the script.js file with the code for creating the input tag
$(document).ready(function(){
var i=1;
$("#add_city").click(function(){
$('#end_city'+i).html('<input type="text" class="form-control input-lg ng-isolate-scope" name="via_city" ng-autocomplete="via_city" placeholder="Travel via" autocomplete="off" />');
$('#tab_logic').append('<div id="end_city'+(i+1)+'"></div>');
i++;
});
$("#delete_city").click(function(){
if(i>1){
$("#end_city"+(i-1)).html('');
i--;
}
});
});
And there is the index.php
<div class="page-header">
<h4>Create your trip</h4>
</div>
<form ng-submit="submitTrip()"> <!-- ng-submit will disable the default form action and use our function -->
<!-- START CITY -->
<div class="form-group col-md-6">
<input type="text" class="form-control input-lg" name="start_city" ng-autocomplete="tripData.start_city" placeholder="Travel from">
</div>
<!-- END CITY -->
<div class="form-group col-md-6" id="tab_logic">
<div id="end_city0">
<input type="text" class="form-control input-lg" name="end_city" ng-autocomplete="tripData.end_city" placeholder="Travel to">
</div>
<div id="end_city1"></div>
</div>
<!-- START DATE -->
<div class="form-group col-md-6">
<input type="date" class="form-control input-lg" name="start_date" ng-model="tripData.start_date" placeholder="Travel date">
</div>
<!-- END DATE -->
<div class="form-group col-md-6">
<input type="date" class="form-control input-lg" name="end_date" ng-model="tripData.end_date" placeholder="Return date">
</div>
<!-- COMMENT -->
<div class="form-group col-md-12">

</div>
<!-- Img -->
<div class="form-group col-md-12">
<input type="text" class="form-control input-lg" name="img" ng-model="tripData.img" placeholder="Image source">

You need to compile the element by using the $compile service:
...
$('#tab_logic').append('<div id="end_city' + (i + 1) + '"></div>');
var element = angular.element(document.querySelector('#end_city' + i));
var scope = element.scope();
var $compile = element.injector().get('$compile');
$compile(element)(scope);
...
Good short explanation of how to work with Angular from the 'outside' can be found here.
