如何捕获jqgrid中日期列的dataEvents

Question

您好我有一个jqgrid网格我在下面做。可以帮助我使用DataEvent类型来帮助捕获日期更改吗？

                   {
                    name: "MonthYear",
                    index: "MonthYear",
                    width: 70,
                    align: "center",
                    sorttype: "date",
                    editable: true,
                    editrules: {
                        required: true
                    },
                    editoptions: {
                        dataInit: function (e) {
                            Utility.customDatePicker(e);
                        },
                        dataEvents: [
                          {
                              **type: "changeDate",**
                              fn: function (e) {
                                  // -- need to do some calculation on basis of Date change
                              }
                          }]
                    },
                    formatter: "date",
                    formatoptions: { srcformat: "M/Y", newformat: "M/Y" },
                },

我做了以上但我无法捕获dateChange事件，因为我需要根据更改时捕获的日期进行一些计算。谢谢
