Now, I see what you are trying to do, you are trying to implement
a SeasideAsync missing piece.
Actually, I have had a for a long time, the project of finishing
adding live callbacks to radio buttons, date and time input and maybe
a few other smaller things. If found it not trivial and I gave up.
I will look if I can restart this project and let you know.
