KendoUI Mobile DropDownList in Icenium Mist

Hello!
I'm developing a simple app using Icenium Mist. I followed the example on mobile forms page about drop-down list:
http://demos.kendoui.com/mobile/forms/index.html

In the demo it works fine - the drop down shows up and stays there. In my app I can see the drop-down list show for a split second, and it disappears right away. I didn't see any JS errors or missing references.

Markup is simple:
<div data-role="view" data-init="initSignOffForm">
.....
<select id="ddlChild">
<option value="1">Veronique</option>
<option value="2">Michelle</option>
        <option value="3">Griffin</option>
        <option value="4">Boris</option>
</select>
.....
</div>

Then my JS file piece copied from demo page:

function initSignOffForm(){
    var body = $(".km-vertical,.km-horizontal");
    if (kendo.ui.DropDownList) {
        $("#ddlChild").kendoDropDownList({
                // The options are needed only for the desktop demo, remove them for mobile.
                popup: { appendTo: body },
                animation: { open: { effects: body.hasClass("km-android") ? "fadeIn" : body.hasClass("km-ios") ? "slideIn:up" : "slideIn:down" } }
            });
    }
}

I tried removing the options for the list in JS - same thing...

Compiled and tested in on the phone - blinks the same way as well.

Anyone knows why and how to fix?
