title: jQuery toggle() with toggleClass()
body: <p>I have a button that toggles a DIV layer on and off.   I am trying to add a class to the button so that when its toggled on it appears differently, however I haven't been able to get it working, the class is not being added when the button is toggled.</p>
  
  <p>The button is a list item e.g. On / Off</li></p>
  
  <p>Here is my code:</p>
  
  <pre><code>$("#btninformation").click(function () {
    $("#map-items-category-one").toggle("slow", function() {
      $(this).toggleClass("toggled-on");
    });
  });
  </code></pre>
  
  <p>Any ideas whats wrong with it?</p>
  
  <p>Thanks
  Zach</p>
