title: fndraw on datatables not working
body: <p>I'm using the datatables plugin and want to reload the sorting of the table columns by the click of a button. I'm changing the content of the table clientside. But nothing happens when I click redrawBtn. Everything else is working properly.</p>
  
  <pre><code>// datatable config
  var oTable = tablesorterEl.dataTable({
  "bPaginate": false,
  "bLengthChange": false,
  "bFilter": true,
  "bSort": true,
  "bInfo": false,
  "bAutoWidth": false,
  "bRetrieve": false,
  "asSorting": true,
  "bServerSide": false,
  "bSearchable": true,
  "aaSorting": [],                    
  "oLanguage": {
  "sSearch": ""
  },
  "bStateSave": true
  });
  
  // redraw button
  $('.redrawBtn').click(function(){
  
    oTable.fnDraw();
  });
  </code></pre>
