Accessing ember session content from within a route

I've an ember-cli app that is using ember-simple-auth.

I created a custom initializer to inject a currentUser object in

import Ember from 'ember';
import Session from 'simple-auth/session';

export default {
  name: "current-user",
  before: "simple-auth",
  initialize: function(container) {
    Session.reopen({
      setCurrentUser: function() {
        var accessToken = this.get('secure.token');
        var _this = this;
        if (!Ember.isEmpty(accessToken)) {
          return container.lookup('store:main').find('user', 'me').then(function(user) {
            _this.set('content.currentUser', user);
          });
        }
      }.observes('secure.token'),
      setAccount: function() {
        console.log(this.get('content.currentUser'));
        var _this = this;
        return container.lookup('store:main').find('account', this.get('content.currentUser.accountID')).then(function(account) {
          _this.set('content.account', account);
        });
      }.observes('content.currentUser'),
    });
  }
};

I can access the currentUser properties in my templates with {{session.content.currentUser.email}} I can't figure out how to access it in the route...

import Ember from 'ember';
import AuthenticatedRouteMixin from 'simple-auth/mixins/authenticated-route-mixin';

export default Ember.Route.extend(AuthenticatedRouteMixin, {
  model: function() {
    console.log(this.get('session.content')); // valid
    console.log(this.get('session.content.currentUser')); // undefined
    return Ember.RSVP.hash({
      layouts: this.store.find('layout', { account_id: 1}),
    });
  },
  setupController: function(controller, model) {
    controller.setProperties(model);
  },
});

Can anyone put me out of my misery?

Thanks :)
