KENDO UI TEMPLATE FUNCTIONING BASIC QUESTION

[Saurabh]

When is javascript within a template executed? Is it rendered every time the data binding occurs or is it only once? 

Example - 

<script id="demoTemplate" type="text/x-kendo-template">

#if(person) {

   <h1>${person.name}</h1>

}

else {

   <h1>${id}</h1>

}#

</script>

    <script>


var data = [{"person":{"name":"saurabh"},"id":123},{"id":123}]

        window.kendoMobileApplication = new kendo.mobile.Application(document.body);

        $(document).ready(function () {

$("#listUL").kendoMobileListView({

                template: $("#demoTemplate").text(),

                dataSource: data

            });

}

</script>

So I want to show ID field when person object is missing in the JSON data. I get following error when I run it - "person variable is missing"

How do I handle missing variables in templates? How can I check for them?

[Saurabh]

Could someone at Kendo reply to this? This is critical. How do we handle data if it is null or missing in the binding within a kendo template?
