Alarm clock example does not refresh in iOS app

I am trying to use the alarm clock example II posted here:

It works great in the web UI but in the iOS interface you have to return to the previous leve and come backl in order to refresh the displayed time after changing the hours or minutes.

Any idea how one could enforce a refresh in the iOS app?

Looks like it is related to this known problem, take a look at this post (could have been easily found with the search button in this forum).
