Data model is not reacting to model changes

Steps to reproduce

Add two jsoneditors on the same html page and connect them to the same date model.
Change some values in one model and you will see that the other josonditor's model is not updated.

Seems to be old, and recurring Polymer binding issue, please try to addEventListener for change and notify the other elements (apply given patches if needed)

So that's the same issue as Starcounter/DevTools#38.

If I understand correctly, you suggest to solve it in starcounter-debug-aid?
