On Change Perspectives Event not working

I'm not able to fire any event "On Change Perspectives Event".
I have tried from code subscribing to the event handler as explained here:
https://opsive.com/support/documentation/ultimate-character-controller/camera/

No luck. I`ve tried also from the events tab in the Camera Controller component and I don't receive any event.

I'm using lots of events on my scripts (on death, .....) and all of them are working great but this.

Unity 2018.3
Opsive UUC2 2.1.1
Late Update
You can try on the demo scene (tested and doesn't work for me)
 
There are two different events - OnCameraChangePerspectives and OnCharacterChangePerspectives. The former is sent from the camera, the latter is sent from the character. Make sure you are subscribing to the correct event - this event is one of the more popular events so I know that it works :)
 
ok, done. I was looking for the one when you press "V" and it's OnCharacterChangePerspectives
So what is for OnCameraChangePerspectives and when does it get activated? :)
