The bug

/*
  The model is something like:
  Person: { name: String }
  Car: { name: String, driver: {type: Schema.Types.ObjectId, ref: 'Person'} }
*/

// Somewhere we do this…

Sample usage on JSFiddle

Disclaimer

This may be a dumb solution, you'd better use $rootScope.$on(event, handler) and $rootScope.$emit(event, args…) and not use a third-party service.

My solution will bring you:

• support for off() if you really want to clean up your event handlers
• maybe a conceptually better solution than using scopes, as with a service you make yourself independant from your view
