title: JQuery Tablesorter issue
body: <p>I have this table where the  is initially blank. Then when
  the document is ready I call a function that runs an AJAX query for
  the table content.
  The initial content is sorted awesomely! But when I call my function
  again with different parameters to get new content, things start to go
  wrong. The table fills with the new content just fine, but clicking
  on a header column to sort reverts the table content back to what it
  was when the page first loaded and the sorting also stops working.</p>
  
  <p>This is the code snippet that I am using.
  will using $('.tablesorter').trigger("update") help? At what point should i make a call to this?</p>
  
  <pre><code>jQuery(".tablesorter &gt; tbody").load(path, function(){
      jQuery(".tablesorter").tablesorter({
                      onRenderHeader: function (){
                      this.wrapInner("&lt;span&gt;&lt;/span&gt;");
                  }
                  , widthFixed: true
                  , widgets: ['zebra','hovering','selected']
                  , debug: true
                });
  }
  </code></pre>
  
  <p>Thanks,
  MM</p>
