When the target object is an array, the makeObservable method handles updates by also adding:
Sys.Observer.raiseCollectionChanged Method

The following operations are added to any target object by the observer method to manage events:
Sys.Observer.addPropertyChanged Method

The corresponding static methods described above become available as instance methods directly on the target object.
