Ember-Simple-Auth: How to inject token in ajax request

sorry for that (maybe) silly question. Im super new to this topic!

I created a custom authorizer:

    import Ember from 'ember';
    import Base from 'ember-simple-auth/authorizers/base';
    export default Base.extend({
        authorize: function(jqXHR, requestOptions) {
            var accessToken = this.get('session.content.secure.token');
            if (this.get('session.isAuthenticated') && !Ember.isEmpty(accessToken)) {
                jqXHR.setRequestHeader('Authorization', 'Bearer ' + accessToken);
            }
        }
    });

And now i want to include the token in a ajax request in my controller (this is my code without the token send):

// app/controllers/workouts.js
import Ember from 'ember';
import config from '../config/environment';

export default Ember.Controller.extend({
  requestEndpoint: config.ServerIp+'/workouts',
  workouts: function() {
        Ember.$.ajax({
            type: "GET",
            url: requestEndpoint
        }).success(function(data) {
            return data;
        })
  }.property()
});

Thank you very much for helping and understanding this great module!
