How to populate Bootstrap Multiselect with selected values in php?

I am trying to populate Bootstrap multiselect , I used the following code html

<form>
   <tr>
      <td><label>Code Planteur :</label></td>
      <td> <input type="text" id="code_planteur" name="code_planteur" class="code_planteur"></td>
   </tr>
   <tr>
      <td><label>Numero de Ticket :</label></td>
      <td><select id="num_ticket" name="num_ticket" class="num_ticket">
          <option value="0"> numero de ticket </option>
          </select></td> 
   </tr>
</form>

and my php file ticket.php

<?php
    require 'conn.php';
        if($_POST['id'])
       {
            $id=$_POST['id'];
            $req="select column from table where code_planteur='".$id."' ";
            $req = $pdo->query($req);
            $results = array();
                while($row=$req->fetch())

                    {
                      $data=$row['column'];
                      echo "<option value=".$data.">".$data."</option>";
                    }

        }
?>

my javascript

$(document).ready(function(){
$(".code_planteur").change(function(){
     var id=$(this).val();
     var dataString = 'id='+ id;
$.ajax({
     type: "POST",
     url: "ticket.php",
     data: dataString,
     cache: false,
     success: function(html){
$(".num_ticket").html(html);

                        $.each(data, function (key, val) {
                        $("#num_ticket").append('<option value="' + val + '">' + val + '</option>');

                    });

                         $("#num_ticket").attr('multiple', 'multiple'); 
                         $("#num_ticket").multiselect(); 



                    }

        if($_POST['id']){

          $id=$_POST['id'];
          $req="select num_ticket from paiement where code_planteur='".$id."' ";
          $req = $pdo->query($req);

             while ($row=$req->fetch() ){

                 $resultat[] = $row['num_ticket'];
                } 

             echo json_encode($resultat);

        }
