Updating a value from a hash trigger observer on the whole hash

[cbou]

I observe a particular property of a hash. When I update another property of this hash, then the observer of the first property is triggered. It seems wrong to me.

Here is a sample code:

components/test-macro.js

import Ember from 'ember';
import {hash} from 'ember-awesome-macros';

export default Ember.Component.extend({
	foo: hash({
		prop1: 'prop1',
		prop2: 'prop2'
	}),
	
	prop1: 'hello',
	prop2: 'world',
	
	fooObserver: Ember.observer('foo', function() {
		console.log('Hello foo!');
	}),
	
	prop1Observer: Ember.observer('foo.prop1', function() {
		console.log('Hello foo.prop1!');
	}),
	
	prop2Observer: Ember.observer('foo.prop2', function() {
		console.log('Hello foo.prop2!');
	}),
	
	actions: {
		updateProp1: function() {
			this.set('prop1', 'bonjour');
		}
	}
	
});

templates/components/test-macro.js

{{foo.prop1}} {{foo.prop2}}

<button {{action 'updateProp1'}}>Update prop1</button>

When I click on Update prop1 the console prints:

Hello foo.prop1!
Hello foo.prop2!
Hello foo!

I would actually only expect prop1

I'm not sure how to solve this, since I don't have reference to the previously created object. The macro creates a new one every time.
