Hmmm … not sure it’s possible since I’m not sure the actions are performed before or after the popup is closed. I think after and as such no interaction can happen with the models in the page include.
There’s a custom popup controller that disables Cancel to Close and Removes the X in the corner. That way only a button from the page include can close the popup. You can find it here. Barry Schnell made it I’ve used to learn about custom components ever since.
