I have a custom theme that I want to use for a dojomobile app in worklight. How do I force worklight to use it no matter what the device it is running on? I've tried the following and none work. It keeps going back to the device default.

```
<script src="dojox/mobile/deviceTheme.js" data-dojo-config="mblUserAgent: 'myui'"></script>

<script type="text/javascript" data-dojo-config="isDebug: false, async: true, parseOnLoad: true, mblHideAddressBar: false, mblUserAgent:'myui'" src="dojo/dojo.js"></script>

```
