title: jquery addClass and removeClass issues
body: <p>I am having strange issues with jQuery and adding and removing classes. I'm trying to see on success of a json request, that for the particular hyper link, it should call <code>addClass</code> and <code>removeClass</code> to add/remove particular css properties. When I click on it, it NEVER works, but when I try the css classes independently, they work fine. Is there something I'm missing here? Thanks for the input.</p>
  
  <pre><code>$(document).ready(function() {
      $('.add_link').bind("click", function(e) {
          $.getJSON("/add/", function(json) {
              if (json.SUCCESS != null) {
                  $(this).removeClass('blue_button_link').addClass('gray_out_button_link');
              }
          });
      });
  });
  </code></pre>
