There is already a similar function in Delphi in IBX (IBEvents) that
listens for events, which means it is probably already part of the
API, so don't reinvent the wheel.

My first warning would be that your callback function will not see
your data until after you commit the first transaction. I don't know
whether an event is fired immediately, or after you commit, so you
will need to look that up.
