I finally contacted the Inductive team. Here is the solution they provided, which works perfectly.

It’s possible to catch the modification events of a custom tag property and the editing events of a tag via the Edit (Raw) using the new tag actor factory API.  
Essentially, you just need to register your own tag actor factory that specifies which properties you are interested in subscribing to.  
You can subscribe to any property including custom properties.

I put you the example provided in attachment.
