just register the onOpen event it will also fire when the popup closes.

here a very simple example for a popup being used as a tooltip printing the open state to the console:

<label value="hover" tooltip="pop"/>
<popup id="pop" onOpen='System.out.println("popup open: " + event.isOpen());'>popup text
</popup>

Of course you can listen to this event in a Composer or send a command to a ViewModel.

in Composer (MVC)

@Listen("onOpen=#pop")
public void onPopupChanged(OpenEvent event) {
  if(!event.isOpen()) {
    System.out.println("popup closed");
  }
}

in zul File (MVVM)

onOpen="@command('popupChanged', open=event.open)"

in ViewModel

@Command("popupChanged") 
public void onPopupChanged(@BindingParam("open") boolean open) {
  if(!open) {
    System.out.println("popup closed");
  }
}
