Uncaught TypeError: Cannot read property 'checked' of undefined

[Kevin]

Hi,


I am using the popover with listview and checkbox or radio items. With radio everything works finde, but when I am using checkboxes I get the Error: Uncaught TypeError: Cannot read property 'checked' of undefined
Any idea, what could be wrong? I am creating the Items like this:

$this.children().each(function (i) {

    var $item = $("<li><label>" + $(this).val() + " <input type=\"" + (base.multiple ? "checkbox" : "radio") + "\" " + (this.selected ? "checked=\"checked\"" : "") + " /></label></li>");

    listview.prepend($item);

    var that = this;

    $item.on("click", function () {

        console.log("test");

        that.selected = true;

        $this.ButtonCombobox("setSelection");

    })

});

The error is thrown before output "test" and is thrown by kendo.mobile.min.js.
