Alert box via update callbacks

[mvahowe]

I would like to add an "Are you sure" confirmation alert before deleting. onDelete feels like the place to do this, but I can't see how to handle the Alert UI interaction within the callback. Is there a boilerplate way to implement this kind of thing?

Yeah, this has come up before. It's a little tricky, but there's some suggestions on this issue that might help: #117
