title: Webix Component not getting refreshed
body: <pre><code>function update_grouplist_items(){

  $.ajax({
      type: "POST",

          withCredentials: true
      },
      beforeSend: function(request){
          request.setRequestHeader("Content-type", 'application/json');
      },
      cache: false,
      url:savedataUrl,

  </code></pre>
  
  <p>I am trying to reload the "cfg" component(list) on success. I see that it gets refreshed (new item is added) when I keep the debugger console open. But when the console is closed I see the component getting refreshed but no item added to the list. (Basically I would see the component flicker). I am using Internet Explorer as my browser. Any help would be appreciated.</p>
