$timeout() doesn't update the model

$timeout() doesn't update the model in this demo while $apply() does.

Really weird behaviour.

[leefernandes]

$timeout() has a third boolean parameter to specify whether it should invoke an $apply.

Actually difficult value is true, so it should work, but regardless of what
you put there it does not. I think it may be a race condition, but have not
looked into it deep enough.

As can be seen here

https://github.com/angular/angular.js/blob/master/src/ng/timeout.js#L49

$timeout calls $apply on the root scope, which might explain why the age isn't updated.

Ignore my last comment, of course running $apply on the root scope should update all the child scopes too.

Interestingly if you add {{age}} to the template in the directive, it seems to work okay. Alternatively adding scope.$watch('age'); to the link function makes it work also.

I think the problem might be that because age isn't used in the template, no watch is set up and so updating it doesn't do anything.

Bug in the compiler, I take care of it.
