column sorting with datatables on checkbox

data_sort_checkbox

  /* Create an array with the values of all the checkboxes in a column */
    $.fn.dataTableExt.afnSortData['dom-checkbox'] = function  ( oSettings, iColumn )
    {
        return $.map( oSettings.oApi._fnGetTrNodes(oSettings), function (tr, i) {
            return $('td:eq('+iColumn+') input', tr).prop('checked') ? '1' : '0';
        } );
    }


    $('.ratemgr-table').dataTable({
        "aoColumnDefs": [
            { "bSortable": false, "aTargets": [ "action" ] },
            { "sSortDataType": "dom-checkbox", "aTargets": [ "enabled" ] }
        ],
        "aaSorting": [
            [ 3, "desc" ]
        ]
    });
    
In the view I have this to enable me to put the checkbox in different columns (not tied to col number): 

    <th class="enabled">Enabled</th>
