Can't change adapter host with Ember

I've read Ember docs about this and I know that I have to use custom RESTAdapter and set it to App.Store. I did it and it changes namespace but, it doesn't work with host (it still makes request to current domain).

App.ApplicationAdapter = DS.RESTAdapter.extend({
  host: 'https://api.example.com',
  namespace: 'kraken'
});

App.Store = DS.Store.extend({
  adapter: App.ApplicationAdapter
});


App.IndexRoute = Ember.Route.extend({
  model: function() {
    return this.store.find('game');
  }
});

And request is being made to current domain instead to https://api.example.com
