I know it's not officially supported, but when you use it in hybrid mode in an iOS UIWebView, the events sometimes seems to get mixed up. Then when you clic on a filed, it jumps to the the next one while flashing the keyboard. It doesn't happen always, but just clicking in a few fields on a form and it starts. We had to rollback using it in our codebase. I have a video of the behavior and the code (based on your mobile sample).
