  formatter: function (value) {

                            var date = eval('new ' + value.substr(1, value.length - 2));

                            var year = date.getFullYear();

                            var month = date.getMonth() + 1;

                            var day = date.getDate();

                            return year + "-" + (month < 10 ? ("0" + month) : month) + "-" + (day < 10 ? ("0" + day) : day);
                        }

formatter: function (value, row) {

                             return parseFloat(value).toFixed(2) + "%";
