I have an `ArrayController` that uses associated `itemControllers` to track a `checked` property on the set of models (i.e. whether or not their checkbox is checked).
This part is currently working fine. When I come back to the route, I need to use some information off of the `user` model to “remember” which were checked.
How can I set the `checked` property on the specific `itemController`’s? I can get references to the individual models that need “checking”, but `model.set('checked', true)` doesn’t seem to get picked up by the `itemController` in that scenario.
Any help would be appreciated!
P.S. I’m trying to set this from the route.

I’ve figured out a way to do it by accessing the `itemControllers` as `controller.get('_subControllers')`. But I feel like someone is going to tell me I shouldn’t be doing that.

Yeah, that’s wrong. You have access to all your favorite array functions on the ArrayController that will let you filter, enumerate, through the underlying controllers w/o accessing \_subControllers.

Thanks @jasonmit! I think the issue was that I was trying to do operations on the _content_, rather than the _controller_. i.e. `controller.get('content').forEach(function().....` rather than `controller.forEach(function.....`
