Event not fired when pop-up is opened

I want to fire an event when the user clicks anywhere inside this div :

Usually when a user clicks inside the div, a pop-up opens in the website. I want to fire the event just before that.

I created an Event Rule with the following configuration :

What happens now is, whenever I click inside the div, no event is fired.

When I click in the area of the div that does not open the pop-up, the event is fired.

What causes this problem? Is it related to the pop-up?

Any help would be appreciated.
