Kendo-UI-Grid-template 模板列不能及时刷新问题

 var ShowAlarmColor = new Jfunction(J.use.dataItem)
            {
                J.debugger,
                (J.var.colStyle="<div style='background: #eeeeee;margin:0px; padding:0px'> " + J.use.dataItem.CheckStandard + "</div>"),
                new Jswitch(J.use.dataItem.ALARMLEVEL)
                {
                       new Jcase(0){ (J.use.colStyle="<div style='background: #eeeeee;margin:0px; padding:0px'> " + J.use.dataItem.CheckStandard + "</div>"),J.@break},
                       new Jcase(1){ (J.use.colStyle="<div style='background: #00FF00;margin:0px; padding:0px'> " + J.use.dataItem.CheckStandard + "</div>"),J.@break},
                       new Jcase(2){ (J.use.colStyle="<div style='background: #FFFF00;margin:0px; padding:0px'> " + J.use.dataItem.CheckStandard + "</div>"),J.@break},
                       new Jcase(3){ (J.use.colStyle="<div style='background: #FFAAFF;margin:0px; padding:0px'> " + J.use.dataItem.CheckStandard + "</div>"),J.@break},
                       new Jcase(4){ (J.use.colStyle="<div style='background: #FF3333;margin:0px; padding:0px'> " + J.use.dataItem.CheckStandard + "</div>"),J.@break},
                },
                J.@return(J.use.colStyle),
            };

修改数据源后调用refresh方法 
grid.GetJQuery().refresh(),
