title: Datatable: sorting not working
body: <p>Please help. I am not sure where I am going wrong
  I want the table to be sorted by the first column. I tried several variations, but sort is not working properly</p>
  
  <pre><code>dataTable = $("#deptDtTable").dataTable({
          "bFilter" : false
          "bProcessing" : true,
          "bServerSide" : true,
          "bSort" : true,
          "bStateSave" : false,
          "iDisplayLength" : 25,
          "iDisplayStart" : 0,
          "fnDrawCallback" : function() {
          },      
          "sAjaxSource" : "/url/url/datatable/dept",
          "aaSorting": [[ 1] ],
          "aoColumns" : [ 
              {
              "mData" : 'id'
          }, {
              "mData" : 'client_name' 
          }, {
              "mData" : 'ssn'
          }, {
              "mData" : 'department'
          }, {
              "mData" : 'account_id'
          }, {
              "mData" : 'dateEntered', 
              "render" : function(data) {
                  if (data !== null) {
                      var date = new Date(data);
                      return date.toLocaleString();
                  } else {
                      return '';
                  }
              }
          } ]
      });
