I made only a copy from the python docs for show the "problem".

Ok, I have not understand the "trickle" for transform the
action="callback" and provide a callback to a new action.

I believe, however, that the doc has to be more explicit about this
strange behavior, because a not so expert dev (like me :) ), can don't
understand at the first time, it.
