controllers that talk to loginstate

applicationcontroller.js

//Application controller, since we want login to be an application wide thing
  //login/logout events are bubbled up to here regardless of the page you are on
  App.ApplicationController = Em.Controller.extend({

      authStateBinding: Ember.Binding.oneWay('App.LoginStateManager.currentState.name'),
      authState: null,

      isAuthenticated: function () {
          return (this.get('authState') == 'isAuthenticated');
      }.property('authState'),
      login: function(provider) {
        client.login(provider).then(function(results) {
          App.LoginStateManager.send("login", client.currentUser);
        });
      },
      logout: function() {
        client.logout();
        App.LoginStateManager.send("logout");
      }
  });

newpostcontroller.js

// Newpost controller
