title: DataTables ServerSide sort not working - mDataProp
body: <p>I have the following datatable created with server-side processing enabled:</p>
  
  <pre><code>$(document).ready(function() {
      oTable = $('#example').dataTable( {
          "bServerSide": True,
          "sAjaxSource": "source.php",
          "aaSorting": [[0,"asc"]],
          "aoColumns": [
              { "mDataProp" : "Name",
                 "sType": "string-case" },
              { "mDataProp" : "Priority",
                 "sType": "string-case" },
              { "mDataProp" : "Action",
                 "sType": "string-case" }
          ]
      } );
  } );
  </code></pre>
  
  <p>Name, Priority, and Action are all strings I would like to sort on.  Whenever I click on the column header it does nothing but reload the table.  Probably a stupid question, but do I need to do all my sorting serverside (using the iSortCol_0 and sSortDir_0 as my identifiers)?  Is it possible to sort clientside without refreshing the table like this and actually have it sort based on the names?</p>
