How to display a table in a popup box with JavaScript?

I have the form below, with 4 comboboxes "Metier" "tache" "tacrification" et "technicien", I select a Metier and a tache, after this I want that a popup box appears and show me a table that contains all the "techniciens" and their "tarification" (of course only the "techniciens" that are related with the "tache" already selected.)
After this I select a "technicien" from that table a now the form is completely filled with the "technicien" and it's "tarification".
iterventioncontroller
public function create()
{
$client = client::orderBy('id', 'asc')->get();
$metiers = metier::orderBy('id', 'asc')->get();
$technicien = Technicien::orderBy('id', 'desc')->get();
$tarifications = tarificationtache::orderBy('id', 'desc')->get();
return view('intervention.create')->with('technicien', $technicien)-
>with('client',$client)-
>with('metiers',$metiers)->with('tarifications',$tarifications);
}

It loading into modal via script
Here is script code
$(document).on('click', '#addShow', function () {
ShowAndPopulate();
});
function ShowAndPopulate() {
$('#addProposalManager').load('/Manage/AddProposalManager', function () {
let email = $('#userId').text();
let getProposalsUrl = '/manage/populateprojects';
model = {
email: email
},
$.ajax({
url: getProposalsUrl,
data: JSON.stringify(model),
contentType: 'application/json; charset=utf-8',
type: 'POST',
dataType: 'json',
processData: false,
success: function (data) {
var list = data;
$.each(list, function (i, d) {
$('#projectId').append('<option value="' + d.Id + '">' + d.Name + '</option>');
});
}
})
});
}
Also in this field
#Html.DropDownList("Service", null, "XXXX", htmlAttributes: new { #class = "form-control", #id = "serviceIdProject" })
I need to do something on value change
So I wrote this code at script
$('#serviceIdProject').change(function () {
alert("Gotcha!");
// ServiceChange();
});
But when I change value, nothing happens.
Where can be my problem?
Thank's for help

Try using event delegation and also you seem to be using the wrong ID for the select:
$(document).on('change' , '#projectId' , function () {
alert("Gotcha!");
// ServiceChange();
});

Write a validate function which actually checks for empty value in textbox and returns true or false. Consider below example.
function ValidateForm(form){
var valid=true;
$(form).find('input[type="text"]').each(function(){
if($(this).val()=="")
valid=false;
});
return valid;
}
function save_user_new() {
//getting all the values
//change if condition to
var form=$("#form_sample_1");
if(ValidateForm(form))
{
//continue with ajax
}
else
{
alert('Please fill all the fields');
return false;
}
}

Add jQuery required in save_user_new function
$("input").prop('required',true);

There is a couple of ways to do this.
As previously mentioned, write a validate method and check if the record already exists in the database.
Set the field to 'unique', and catch the error when you run the query,
also if you want to save yourself some time and coding write a helper function which will load all your post variables for your.
eg.
function LoadPostVariables($variables = [])
{
$CI = & get_instance();
$return_array = [];
foreach($variables as $key){
$p_val = $CI->input->post($key);
//you could perform some basic validation here
$return_array[$key]=$p_val;
}
}
$values = LoadPostVariables(['MNumber', 'email', 'fname', 'address', 'sitename', 'title', 'descr', 'uniquekey']);

public function AddUser($data_save)
{
$check = false;
$query = "SELECT * FROM users WHERE email='$data_save' LIMIT 1";
$result = mysqli_query($dbc, $query);
if($result){
while($row = mysqli_fetch_assoc($result)){
$check = true;
}
}
if($check == false){
// add data
}else{
echo 'Email already found'; exit();
}
}
