This is necessary because onChange: does not always update geocoding to 1.0, despite it being 1.0
Instead of trying to pass the properties from VaultModel to NearbyModel and assuming that works (is this a bug???), have NearbyModel have a VaultModel to just get the property values directly.
Looking for a way to have two Observable models where they can be independent instead of dependent. Not now, however.
This was a bug in #726 that was not observed right away. :(
