Observing Why onChange is fired

[tehpsalmist]

When listening in the onChange callback, there is a path property on the changes objects. However, that path property will only include paths at the level of where the active listeners are attached (pardon the non-technical description). How can I listen to my entire observable (a fairly deep object) so that I know what changed everytime a change emitted. I'd like to get that path at its full depth every time. Is this possible? Maybe I used something wrong?
