[Maya] How to know if a new shot in camera sequencer has been created?

Hi guys, after a few years working with 3ds max as main package, I started to work with Maya. It feels like starting from zero sometimes.
In this case I’m trying to add some funcionality to the camera sequencer included in maya but I would need have some way to maya ‘notify me’ when a new shot is created. I thought maybe an script job could do the thing, but I can find which event could do this. Clip nodes passes undetected with the event DagNodeCreated. It’s probably also posible other aproach would be easier/wiser. Anyway any help/guidance on this would be greatly appreciated.
Thanks in advance.
