is necessary to return the value current, rowCount？？？

[scai2013]

i guess it isnot necessary to return the value current, rowCount. while using adjax, when response return back, the request is contaning the value of current and rowCount.

            var settings = {
                url: url,
                data: request,
                success: function(response)
                {
                    that.xqr = null;

                    if (typeof (response) === "string")
                    {
                        response = $.parseJSON(response);
                    }

                    response = that.options.responseHandler(response);

                    that.current = response.current;
                    update(response.rows, response.total);
