[Seaside] onClick vs callback

That depends on the scheduling algorithm of the JavaScript engine.
Generally all AJAX requests run asynchronously, therefor it is not
possible to give any guarantees when and if a response is coming back.
That's why there are callback handlers, such as #onCompleted:,
#onFailed:, #onSuccess:, etc.
