Router passing wrong model to setupController

If anyone familiar with that I have route:

export default Route.extend({
  model: function (params) {
    return Ember.RSVP.hash({
      'category': this.store.peekRecord('category', params.id)
    });
  },
  setupController: function(controller, model) {
    console.log('---',model);
    this._super(controller, model);
  }
});

When route executing I receive strange behavior:

• first load works fine, model contain {category: my model Class}

• second reloading of this route return only model Class without category key.

Environment:

• Ember : 3.0.0

• Ember Data : 3.0.1
