It seems that I can only use the built-in data icons from Kendo UI in my mobile app on my layout page. The navigation menu, defined in the layout page, uses the data icons and they work.
<div data-role="tabstrip" id="navigation-container">
<a href="components/home/view.html" data-icon="home"><span class="navigation-link-text" data-bind="text: strings.home.title"></span></a>
But when I try to use data icons in any other page/view in my app, they don't show up. It seems like the tag isn't even recognized, and therefore the icons aren't added in by the Kendo JS/CSS.
For example, I try this:
<div id="globe" data-icon="globe"></div>
And when I load the view and inspect the page, I see that it is left exactly like that, instead of adding in the <span> to display the data-icon.
It should add the following inside my div: <span class="km-icon km-home"></span>. But it is not happening.
