I actually did read that section more than once, but the JSNI notes are sparse, and there are no event handler samples. I just regenerated my app in detail mode to look for similar generated code, and I do see a few, but I don't understand it. I'll have to take this one on faith; it's not at all clear to me what it's doing.
