Cascading list with leftjoin and Where clause

Good morning,

how to make sure that the Where clause is taken into account, perhaps it is badly positioned?

Javascript :

var editor; // use a global for the submit and return data rendering in the examples
 
$(document).ready(function() {
    editor = new $.fn.dataTable.Editor( {
