    I start with a listview that contains all states with a click event on each to build event headers by state (below). Once a state is selected, ​I fetch event headers and build another listview using this function. Once an event header is selected, I populate a detail page. When loading fresh and selecting a state (Arkansas), the listview is populated and selecting an event populates the detail screen as expected. Hitting the "back" button (data-role=backbutton), selecting another state, then an event for that state throws e.dataItem undefined in the click ​method of the function below. If I go back again, select another state, then sometimes it works, sometimes it doesn't. What am I doing wrong here?

    function BuildEventHeadersListByState(abbr)
        var stateAbbr = abbr;
        var xml;
        var template = kendo.template($("#ulEventHeaders-template").html());
        var dataSource = new kendo.data.DataSource({
            transport: {
                read: function(options){
                $.ajax( {
                    type: "GET",
                    url: "http://xxx.xxxxx.xxx/DuMobileService/GetEventHeadersByState",
                    data: { "apikey": apiKey, "stateAbbreviation": stateAbbr},
                    dataType: "text",
                        success: function(result) {
                            app.view().header.find(".km-navbar").data("kendoMobileNavBar").title(abbr + " Events");
            schema: {
                type: "xml",
                data: "/ArrayOfEventHeader/EventHeader",
                model: {
                    // configure the fields of the object
                    fields: {
                        EventCity: "EventCity/text()",
                        EventDate: "EventDate/text()",
                        EventID: "EventID/text()",
                        EventTitle: "EventTitle/text()",
            dataSource: dataSource,
            template: $("#ulEventHeaders-template").text(),
            dataBound: function(){
                this.scroller().reset(); //scroll to top
            click: function(e){
                var eventID = e.dataItem.EventID;

    Hello Robby Parker,


    First of all apologies for the delayed reply.


    I have tried to reproduce the issue but to no avail. Would it be possible to provide a runnable sample that we can look at and advise your further? You can use Kendo UI Dojo for this.
