Using SC.outlet to connect objects created at runtime to other views/controllers

outletTest.js

MyApp.TestView = SC.View.extend({
	internalTestSet: SC.Set.create(),
	testSet: SC.outlet('internalTestSet')
});

MyApp.TestController = SC.ObjectController.extend({
	testSetBinding: 'MyApp.TestView.testSet'
});

// at console:
testView = MyApp.TestView.create();
testController = MyApp.TestController.create();
testView.get('testSet').toString(); // returns "SC.Set<>"
testController.get('testSet').toString() // returns TypeError: Result of expression 'testController.get('testSet')' [undefined] is not an object.
