data can do crud on the first page while on the second page and the next page does not work

Hello i have a little problem here, when i want to edit or delete my data on next page but my buttons is doesnt work, i just use datatables and modal, but this is very weird because i can edit and delete my data on the first page that just show 10 data.

Here for my script :

<script type="text/javascript">
            $(document).ready(function(){
                    $('.delete').on('click',function(){
                    $('#mytable').DataTable();
                    var userid=$(this).data('userid');
                    $('#ModalDelete').modal('show');
                    $('[name="kode"]').val(userid);
                });
            });
</script>

and here for my modal pop up :

    <form id="add-row-form" action="<?php echo base_url().'backend/clients/delete'?>" method="post" enctype="multipart/form-data">
    <div class="modal fade" id="ModalDelete" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
        <div class="modal-dialog">
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                    <h4 class="modal-title" id="myModalLabel">Delete Clients</h4>
                </div>
                <div class="modal-body">
                        <strong>Anda yakin mau menghapus client ini?</strong>
                        <div class="form-group">
                            <input type="hidden" id="txt_kode" name="kode" class="form-control" required>
                        </div>

                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
                    <button type="submit" id="add-row" class="btn btn-danger">Delete</button>
                </div>
            </div>
        </div>
    </div>
    </form>
