TextBlock change event on link

Hey,
Is it possible to catch change event, when user edit TextBlock on Link, so I can process input data with reference to edited link? I mean something like change: function()... on TextBlock.
I can catch this changes in ModelChangedListener, but I couldn’t find way how to distinguish Node textblock change from Link textblock change, or how to get reference to clicked clicked Link in this event.
Thanks!

Perhaps you just want to set: TextBlock | GoJS API

Ah, I overlooked that. Thank you!
