Ember.js overridden controller doesn't reference the original model?

Question

I have an Ember.js route with a renderTemplate that allows the controller/template to be set by the model. I'm able to get the new controller to function, but when the inherited methods are called, it throws errors about not having a reference to the model that should have been supplied by the model method in the route. Here is the route:

App.ActivityRoute = App.GameScreenRoute.extend({
    model: function(params) {
        var lessons = App.getLessons(),
            lessonId = params.lesson_id,
            activityId = params.activity_id,
            lesson = lessons[lessonId],
            activity = lesson ? lesson.activities[activityId] : null;

        if(activity) {
            return activity.load();
        }
        else {
            return Promise.reject();
        }
    },

    renderTemplate: function(controller, model) {
        this.render(model.get("template") || "activity", {
            controller: model.get("controller") || "activity"
        });
    }
});

When model.controller === undefined, the controller used is ActivityController and it's supplied with the model returned by the model method, but if I set model.controller to another controller, the different controller doesn't have a reference to the model returned by the model method.

Is there something I'm missing or not understanding? Any help would be greatly appreciated.

This is because default setupController hook, which is invoked for ActivityRoute sets the model only for the ActivityController.

I believe by overriding setupController hook you will be able to achieve required behavior:

setupController: function(controller, model) {
    this.controllerFor(model.get("controller") || "activity").set('model', model);
}

I'm not 100% sure if it will work, the controllers must be instantiated somewhere in order to be provided by model. But I guess you have already taken care about that.
