First make sure you're using the latest supported Kendo UI version (2013.2.729). Second if you run your app in the Icenium simulator and use the iPhone device simulator - does it work?
If you have an iOS 6+ device at your disposal, you can debug directly on the device (enable Safari Web Inspector first) to find out what is wrong, for more information, please refer to this blog post: Icenium LiveSync - Real Time Testing and Debugging
