title: Why my JQuery code doesn't work after data loading through ajax?
body: <p>I have a tree view with this jquery code :</p>
  
  <pre><code>$(".treeView").on("click", ".CollOpen, .CollClosed", function () {
      $(this).toggleClass("CollOpen CollClosed").nextAll('ul').first().toggle();
  });
  </code></pre>
