jQuery DataTables TableTools Export - get values of checkboxes or radio items

dreadedmanraz

I am using TableTools v2.2.2 and DataTables 1.10.0 and have it successfully exporting some table contents. However, it is not picking up the values from the checkboxes in the table cells. How can I extract the value as true or false (or 1,0; any indicator really) from the cells and make them export?

table = $('#sort1').DataTable({
        stateSave: true,
        filter: false,
        "order": [[sortColumn, "asc"]],
        "pageLength": 25,
        "columnDefs": [
            {
                "targets": ['no-sort'],
                "orderable": false,
            },
        ],         
        "autoWidth": false,
        "tableTools": {
            "aButtons": [               
                {
                    "sExtends": "collection",
                    "sButtonText": "Export",
                    "aButtons": ["csv", "xls", "pdf", "print"],
                    // TODO: Get this working.
                    "fnCellRender": function ( sValue, iColumn, nTr, iDataIndex ) {                     
                        return " TableTools";
                    }
                }
            ],
            "sSwfPath": "/Scripts/plugin/datatables/TableTools/swf/copy_csv_xls_pdf.swf"
        },
        "initComplete": function (oSettings, json) {
            $(this).closest('#sort1_wrapper').find('.DTTT.btn-group').addClass('table_tools_group').children('a.btn').each(function () {
                $(this).addClass('btn-sm btn-default btn-primary');
            });
            if ($('td.dataTables_empty')) {
                $('td.dataTables_empty').parent().hide();
            }
        },
        // This sets the resulting html layout i.e. https://datatables.net/reference/option/dom    
        "dom": "<'dt-toolbar'<'col-xs-12 col-sm-6'f><'col-sm-6 col-xs-6 hidden-xs'lT>r>" +

    });

You can see I've been trying to use fnCellRender and its anoynmous method, but even though I expect it to return " TableTools" for each cell, it returns nothing.
