Multiple Row Delete not working.

[ncdv23]

Hey there.
Is multiple row delete working?
My console keep telling selectedRows.data is not a function

        onDeleteRow: function(datatable, selectedRows, success, error) {
        $.ajax({
            url: 'delete.php',
            type: 'POST',
            data: selectedRows.data(),
            success: success,
            error: error
        });
    }
