ember-cli torii and multiple providers

I am trying to set up an authenticator which would be valid for many providers, because in the backend I am using doorkeeper assertion method which handles the whole flow.

I have installed:

* "ember-cli-simple-auth": "0.8.0-beta.1"
* "ember-cli-simple-auth-oauth2": "^0.8.0-beta.2"
* "ember-cli-simple-auth-torii": "^0.8.0-beta.2"
* "torii": "^0.3.4"

I was looking at this issue Workflow for Ember-simple-auth, Torii and Facebook Oauth2 so I could write this:

# templates/login
<a {{action 'oauth2Authenticate' 'facebook-oauth2'}}>Login with facebook</a>
<a {{action 'oauth2Authenticate' 'google-oauth2'}}>Login with google</a>

# controllers/login
actions: {
  oauth2Authenticate: function(provider) {
    this.get('session').authenticate('authenticator:oauth2', { torii: this.get('torii'), provider: provider });
  }
}

# initializers/authentication
import Oauth2Authenticator from '../authenticators/oauth2';
export function initialize(container) {
  container.register('authenticator:oauth2', Oauth2Authenticator);
}
export default {
  name: 'authentication',
  initialize: initialize
};

# authenticators/oauth2
import Ember from 'ember';
import OAuth2 from 'simple-auth-oauth2/authenticators/oauth2';

export default OAuth2.extend({  
  authenticate: function(options) {
    var self = this;
    console.log(options.provider);
    return new Ember.RSVP.Promise(function(resolve, reject) {
      options.torii.open(options.provider).then(function(data) {
        var data = {
          grant_type: 'assertion',
          provider: options.provider,
          assertion: data.authorizationCode         
        };
        self.makeRequest(self.serverTokenEndpoint, data).then(function(response) {
          Ember.run(function() {
            var expiresAt = self.absolutizeExpirationTime(response.expires_in);
            self.scheduleAccessTokenRefresh(response.expires_in, expiresAt, response.refresh_token);
            resolve(Ember.$.extend(response, { expires_at: expiresAt }));
          });
        }, function(xhr, status, error) {
          Ember.run(function() {
            reject(xhr.responseJSON || xhr.responseText);
          });
        });
      }, reject);
    });
  }
});

# config/environment
ENV['simple-auth'] = {
  authorizer: 'simple-auth-authorizer:oauth2-bearer',
  crossOriginWhitelist: ['*']
};

ENV['simple-auth-oauth2'] = {
  serverTokenEndpoint: ENV.host + '/oauth/token',
  refreshAccessTokens: true
};

ENV['torii'] = {
  providers: {
    'facebook-oauth2': {
      apiKey:      '631252926924840',
      redirectUri: 'http://localhost:4200'
    }, 
    'google-oauth2': {
      apiKey:      '631252926924840',
      redirectUri: 'http://localhost:4200'
    }
  }
};

I am not sure if it is the better way for my requirements, for now I am getting the problem that I cannot run open method of torii, anybody know what I am doing wrong? if you have a better solution to this issue would be very appreciated.
