title: Repopulating a Datatable with new parameters
body: <p>I initialised my table like this</p>
  
  <pre><code>/* POST data to server */
  $(document).ready(function() {
      $('#example').dataTable( {
          "bProcessing": true,
          "bServerSide": true,
          "sAjaxSource": "xhr.php",
          "fnServerData": function ( sSource, aoData, fnCallback ) {
              $.ajax( {
                  "dataType": 'json', 
                  "type": "POST", 
                  "url": sSource, 
                  "data": aoData, 
                  "success": fnCallback
              } );
          }
      } );
  } );
  </code></pre>
  
  <p>Later on, I want to update the data in the table. How do I do that?</p>
