Autonumbering is not working on added rows

I have 2 functions. Add dynamic rows and Autonumbering. My problem is, my autonumbering is not working on my dynamically added rows. I wonder what could be the problem? The "class="form-control" is all the same for my input type field. However, it is still not working. I have provided my js fiddle below.
https://prnt.sc/124vuju
https://jsfiddle.net/rain0221/59k4c0yg/3/ // in "lb" column, type any number and hit ctrl+enter in order to do autonumbering
//this is my function for autonumbering
const inputs = document.querySelectorAll(".form-control");
inputs[0].addEventListener("keyup", e => {
let value = parseInt(e.target.value);
if ((e.ctrlKey || e.metaKey) && (e.keyCode == 13 || e.keyCode == 10)) {
inputs.forEach((inp, i) => {
if (i !== 0) {
inp.value = ++value;
}
})
}
})
//this is my function for adding dynamic rows.
$("#addrow").on('click', function() {
let rowIndex = $('.auto_num').length + 1;
let rowIndexx = $('.auto_num').length + 1;
var newRow = '<tr><td><input class="auto_num" type="text" value="' + rowIndexx + '" /></td>"' +
'<td><input name="lightBand' + rowIndex + '" id="auto" value="" class="form-control" type="number" readonly /></td>"' +
'<td><input id="weight' + rowIndex + '" name="weight' + rowIndex + '" type="number" /></td>"' +
'<td><input id="wingBand' + rowIndex + '" name="wingBand' + rowIndex + '" type="number" /></td>"' +
'<td><input type="button" class="removerow" id="removerow' + rowIndex + '" name="removerow' + rowIndex + '" value="Remove"/></td>';
$("#applicanttable > tbody > tr:last").after(newRow);
});
$(document).on('click', '.removerow', function() {
$(this).parents('tr').remove();
regenerate_auto_num();
});
function regenerate_auto_num() {
let count = 1;
$(".auto_num").each(function(i, v) {
$(this).val(count);
count++;
})

You need to find the elements inside eventListener event. Since you are finding the element global onload so if will not hold the elements added dynamically. You can move the blow code inside addEventListener keyup event.
const inputs = document.querySelectorAll(".form-control");
To attach the keyup event, you can use document.querySelectorAll(".form-control")[0] instead of inputs[0].
document.querySelectorAll(".form-control")[0].addEventListener("keyup", e => {
const inputs = document.querySelectorAll(".form-control");
let value = parseInt(e.target.value);
if ((e.ctrlKey || e.metaKey) && (e.keyCode == 13 || e.keyCode == 10)) {
inputs.forEach((inp, i) => {
if (i !== 0) {
inp.value = ++value;
}
})
}
});
I can see that you have assigned the 'form-control' class only for LB# column so autonumber will be generate only for LB#. In case you want to generate autonumber for all the columns, assign the class="form-control" to each added dynamically.

The problem is that you are addding keyup listeners only to those elements that are already present in the DOM at the time you are adding them.
What you need instead is called delegate listeners, and it means that you rely on the mechanism that most events bubble up in the DOM, allowing you to attach the keyup listener to an element that is an ancestor to all the input elements of interest.
Inside that listener, you then check if the element they event came from is one you want to handle.
//this is my function for autonumbering
const inputAncestor = document.querySelector("tbody");
inputAncestor.addEventListener("keyup", e => {
if (
e.target.matches('input.form-control') &&
((e.ctrlKey || e.metaKey) && (e.keyCode == 13 || e.keyCode == 10))
) {
const inputs = document.querySelectorAll(".form-control");
let value = parseInt(e.target.value);
inputs.forEach((inp) => {
if (inp !== e.target) {
inp.value = ++value;
}
})
}
})
//this is my function for adding dynamic rows.
$("#addrow").on('click', function() {
let rowIndex = $('.auto_num').length + 1;
let rowIndexx = $('.auto_num').length + 1;
var newRow = '<tr><td><input class="auto_num" type="text" value="' + rowIndexx + '" /></td>"' +
'<td><input name="lightBand' + rowIndex + '" value="" class="form-control" type="number" readonly /></td>"' +

Unfortunately, your code has several more problems, which I tried to fix.
As mentioned in the first comment to your question, you cannot have a div as a child of tbody. Only tr is allowed here.
You are using duplicate id value auto. That is invalid HTML.
In your markup, you have the class form-control on all the inputs. In your dynamically added markup it's only on the first input. Which version is the correct one?
In your tfoot you had the button as direct child. This is, again, invalid HTML. The only child element(s) tfoot can have is tr.
The very first row in your table describes the columns and acts as your table's header, yet it did not reside in the thead part of your table.

I want to combine 2 different java scripts

I have 2 java script codes, one work as a search suggestion and second is for adding another form fields dynamically and this second script also calculate values given in input fields, but both scripts have this 'ADD MORE PRODUCT' feature. What i want is; i want to combine both 'ADD more" feature, because 1st script works on id="" tag to identify field to show search result but second script not do it.
Fetching details in first row is successful, but when i click ADD more button populated by second script, it does not work

(CLOSED) When button is clicked, How to Get input values in the 1st table row and display them in the newly added rows

Now, when the ok button is clicked, additional rows will be added below the 1st table row. I'm wondering when the button is clicked,how to get the values from the 1st table row, and add those values to the row(s) newly added (possibly more than 1 row depends on how many row(s) user input.

So i have found this will do what i need , it's likely there's gonna be better answer out there. If u have one, please do share. Thank you
$('#add-row').click(function() {

$tbody = $('table#one tbody ');
$row = $tbody.find('tr:last');
var lastRowIndex = ($row.index() == -1 ? 0 : $row.index()) + 1;
additionalRows = new Array(numNewRows);
for (i = 0; i < numNewRows; i++) {
additionalRows[i] = ` <tr>
<td>${lastRowIndex}</td>
<td>
<input type="text" name="name[]" class="tommy"></td>
<td><input type="text" name="other[]" class="danver"></td>
</tr>`
lastRowIndex = lastRowIndex + 1;
}
$tbody.append(additionalRows.join());
}
});
$("#add-row").on('click', function() {
var set = $('#tommy,#danver').val();
if (set) {
$('.tommy,.danver ').val(set);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Here you go with the solution https://jsfiddle.net/r3rbkf72/1/
$('#add-row').click(function() {
var $tbody, $row, additionalRows;
var numNewRows = parseInt($('#insert-rows-amnt').val(), 10);
if (isNaN(numNewRows) || numNewRows <= 0) {
alert('Please enter number of row');
} else {
$tbody = $('table#one tbody ');
$row = $tbody.find('tr:last');
var lastRowIndex = ($row.index() == -1 ? 0 : $row.index()) + 1;
additionalRows = new Array(numNewRows);
var name = $('table#one tbody td:eq(1) input[name="name[]"]').val();
var other = $('table#one tbody td:eq(2) input[name="other[]"]').val();
for (i = 0; i < numNewRows; i++) {
additionalRows[i] = `<tr>
<td>${lastRowIndex}</td>
<td>
<input type="text" name="name[]" value=${name}></td>
<td><input type="text" name="other[]" value=${other}></td>
</tr>`
lastRowIndex = lastRowIndex + 1;
}
$tbody.append(additionalRows.join());
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="number" id="insert-rows-amnt" name="insert-rows-amnt" value="<?php echo $tam ?>" />
<button id="add-row" type="button">OK</button>
<table id="one">

<td>
<input type="text" name="id[]" value="No"></td>
<td><input type="text" name="name[]" value="Tommy"> </td>
<td><input type="text" name="other[]" value="Danver"> </td>
</tbody>
</table>
Below two lines of code I have added.
var name = $('table#one tbody td:eq(1) input[name="name[]"]').val();
var other = $('table#one tbody td:eq(2) input[name="other[]"]').val();
This will help you to receive the data from the top row textbox.

reading dynamically added input values into an array php

Every thing is working expect that on adding the dynamic fields,the input added is not captured into the array.Only the values in the only created input are read. HTML PART
<table class="table table-bordered table-hover order-list" >
<thead>
<tr><td>Product</td><td>Price (Ksh.) </td><td>Qty</td><td> (Ksh.)</td></tr>
</thead>
<tbody>
<tr>
<td><input type="text" class="form-control" name="product[]" required="" /></td>
<td><input type="text" class="form-control" name="price[]" required/></td>
<td><input type="text" class="form-control" name="quantity[]" /></td>
<td><input type="text" name="linetotal[]" readonly="readonly" /></td>
<td><a class="deleteRow"> x </a></td>
</tr>
</tbody>
<tfoot>
<tr>
<td colspan="5" style="text-align: center;">
<input type="button" id="addrow" value="Add Product" />
</td>
</tr>
<tr>
<td colspan="5">
Grand Total: Ksh.<input type="text" name="grandtotal" readonly="readonly" /><span id="grandtotal"></span>
</td>
</tr>
</tfoot>
</table>
THE javascript to sum up the get the sub total and grand total is as below:
$(document).ready(function () {
var counter = 1;
$("#addrow").on("click", function () {
counter++;
var newRow = $("<tr>");
var cols = "";
cols += '<td><input type="text" name="product' + counter + '"/></td>';
cols += '<td><input type="text" name="price' + counter + '"/></td>';
cols += '<td><input type="text" name="quantity' + counter + '"/></td>';
cols += '<td><input type="text" name="linetotal' + counter + '" readonly="readonly"/></td>';
cols += '<td><a class="deleteRow"> x </a></td>';
newRow.append(cols);
$("table.order-list").append(newRow);
});
$("table.order-list").on("change", 'input[name^="price"], input[name^="quantity"]', function (event) {
calculateRow($(this).closest("tr"));
calculateGrandTotal();
});
$("table.order-list").on("click", "a.deleteRow", function (event) {
$(this).closest("tr").remove();
calculateGrandTotal();
});
});
function calculateRow(row) {
var price = +row.find('input[name^="price"]').val();
var qty = +row.find('input[name^="quantity"]').val();
var linetotal = +row.find('input[name^="linetotal"]').val((price * qty).toFixed(2));
}
function calculateGrandTotal() {
var grandTotal = 0;
$("table.order-list").find('input[name^="linetotal"]').each(function () {
grandTotal += +$(this).val();
});
$("#grandtotal").text(grandTotal.toFixed(2));
}
the php part to read the array is
if(isset($_POST['cinvoice']) && $_SERVER["REQUEST_METHOD"] == "POST" &&is_array($_POST["product"]) && is_array($_POST["quantity"]) && is_array($_POST["price"]) && is_array($_POST["linetotal"]))
{
$recordid="";
$firstname="";
$product="";
$quantity="";
$price="";
$linetotal="";
foreach ($_POST["product"] as $key => $prod) {
$product .= $prod.",";
}
foreach ($_POST["quantity"] as $key => $qty){
$quantity.=$qty. ",";
}
foreach ($_POST["price"] as $key => $prc) {
$price.=$prc. ",";
}
foreach ($_POST["linetotal"] as $key => $linetotal) {
$linetotal.=$linetotal. ",";
}

you should pass textbox name as an array:
cols += '<td><input type="text" name="product[]"/></td>';
cols += '<td><input type="text" name="price[]"/></td>';
cols += '<td><input type="text" name="quantity[]"/></td>';
cols += '<td><input type="text" name="linetotal[]" readonly="readonly"/>
Also you can use implode function in php
foreach ($_POST["product"] as $key => $prod) {
$product .= $prod.",";
}
to
$product = implode(',', $_POST["product"])

javascript function in dynamically input

I'm having an issue using jQuery function multiplication (math) with dynamically created inputs (again created with jQuery). I can't get my function to bind to the new inputs. for the first row its work, but for second row it did not work (second row and more using dynamically input).
Here my html code

Any help is appreciated.

You are not passing current id's of inputs to your sum method. and one more thing add jquery onkeyup event to your dynamic inputs. please refer below code -
$(function() {
$('#sample').on('click',additem)
$( "#nama" ).autocomplete({
source: "get_barang.php",
minLength: 2,
select: function( event, ui ) {
$('#kode').val(ui.item.kode);
$('#harga').val(ui.item.harga);
}
});
});
function sum() {
var hrg = document.getElementById('harga').value;
var jml = document.getElementById('jumlah').value;
var result = parseInt(hrg) * parseInt(jml);
if (!isNaN(result)) {
document.getElementById('total').value = result;
}
}
var i = 1;
function additem() {
//menentukan target append
var itemlist = document.getElementById('itemlist');
// membuat element
var row = document.createElement('tr');
var nama = document.createElement('td');
var kode = document.createElement('td');
var harga = document.createElement('td');
var jumlah = document.createElement('td');
var total = document.createElement('td');
var aksi = document.createElement('td');
// meng append element
itemlist.appendChild(row);
row.appendChild(nama);
row.appendChild(kode);
row.appendChild(harga);
row.appendChild(jumlah);
row.appendChild(total);
row.appendChild(aksi);
// membuat element input1
var nama_input = document.createElement('input');
/*nama_input.setAttribute('id', 'nama');*/
nama_input.setAttribute('name', 'nama_input[]');
nama_input.setAttribute('class', 'form-control');
var kode_input = document.createElement('input');
/* kode_input.setAttribute('id', 'kode1');*/
kode_input.setAttribute('name', 'kode_input[]');
kode_input.setAttribute('readonly', '');
kode_input.setAttribute('class', 'form-control');
var harga_input = document.createElement('input');
harga_input.setAttribute('name', 'harga_input[]');
