Problem getting JQuery data-id value after clicking datatable navigation

I got bug when I use JQuery data-id in jQuery Datatables. For the first 10 (Ten) record working well. But when I click navigation table to enter to the second page, the data-id value not shown. Please see my code below :

<a href="#" class="btn bg-brown" data-toggle="modal" data-target="#modal_theme_custom"><i class="icon-plus2 pr-2"></i> Tambah Data</a>
<table class="table datatable-basic table-striped table-hover">
            
                <thead>
                    <tr>
                        <th class="text-center">#</th>
                        <th>Nama Jenis Obat</th>
                        <th class="text-center">Aksi</th>
                    </tr>
                </thead>
                <tbody>
                    <?php
                    $x = 1;
                    $sdata  = mysqli_query($konek, "SELECT * FROM e_jnsobat ORDER BY nm_jnsobat ASC");

                    while($ddata = mysqli_fetch_array($sdata)) {
                        echo "
                                        <tr>

                </div>

And this is the javascript code:

<script type="text/javascript">
            $(document).ready(function() {

                $('.btedit').on('click', function() {
                    const id    = $(this).data('id');
                    $('#id_jnsobat_edit').val(id);
                    console.log("Datanya : "+id);
                    $.ajax({
                        type: 'get',
                        url: "<?php echo docroot('ajax/jnsobat/'); ?>"+id,
                        async: false,
                        dataType: 'json',
                        success: function(data) {
                            //console.log("Datanya : "+data);

                            $('#nm_jnsobat').val(data[0].nm_jnsobat);
                            
                        }
                    });
                });
            
                
                $('.bthapus').on('click', function() {
                    const id    = $(this).data('id');
                    const nama  = $(this).data('nama');
                    $('#id_jnsobat_hapus').val(id);
                    //$('#nm_userxx').val(nama);
                    document.getElementById("nm_jnsobat_hapus").innerHTML = nama;
                    //console.log("data : " + nama);
                });
                
                
            });
        </script>
        

on the first 10 recode its work well, but when I click button to go to the second page of datatable navigation the data-id dosen’t work… I dont know where is the problem… sory about my English…

Answer

As per the comments above here is the answer…

The below only listens to click events that are rendered before the code is executed.

$('.bthapus').on('click', function() { ... });

Replacing that with the below listens to the click event on the entire document, so dynamically created elements (such as your table pagination) will be included.

$(document).on('click', '.btedit', function() {
