Hi William
Ok, I see what you mean now; the issue is that while qx.data.controller.Object
is being used to bind model.submodel2 to list.model, it does not know anything
about model.submodel2[0].a – it’s never being told to bind that sub-property so
it will never see it change and never report it.
Automatically monitoring sub properties (or sub-sub-properties etc) is not
something that is supported by qx.data.controller.Object, so I’d implement my
own monitoring class – here’s one that I’ve quickly hacked together:

Note that there is no List or Object controller, but FWIW if you want to bind
to a List you need to separately use the qx.data.controller.List, as you can
see here: http://tinyurl.com/zwyvt8u

Subject: Re: [qooxdoo-devel] onUpdate binding callback not called if submodel
has been updated
Hi John,
This is not the problem, as you can see in your updated example, after have
updated the model (line 34), onUpdate() has not be called. This is my problem,
I would like to found a way to be "notified" when the model has changed.

Hi William
The onUpdate method is being called; is it possible that you were looking in
the Playground log and not in the browser log? The Playground log only
includes messages from this.warn() etc (or qx.log.Logger.warn() etc), but
console.log() statements go direct to the browser console.
I’ve updated your sample to use this.warn() and see messages when onUpdate() is
being called: http://tinyurl.com/jhl6uwo
