title: jquery inactive after ajax
body: <p>im using jquery sortable on a list to move the elements around. It works fine to start but I also have an ajax panel on my page that can add new items to the list. Once ajax sends new elements to the list I can no-longer sort it. I have this call:</p>
  
  <pre><code>$("#MainContent_previewlist").sortable({
              update: function (event, ui) { }
          });
  </code></pre>
  
  <p>I am not familiar with javascript. Do I need to call some event to get jquery to evaluate the new list after ajax?</p>
