In canjs 1.1, for new models I think you need to push into the
list. This makes sense, for example, say it is a list of TODO items
that are "Done", CanJS wouldn't automatically
"know" if your newly created model should go in that list or
not. It's up to you to add it to the list, or to call findAll
again (or maybe to bind to the create event and check if the
item.Status == "Done")
For updates, it should definitel update items in the list.
In the background, instances of models are stored in a static hash
object in [Model].store. So..
