[Deleted user]

In Lesson 3 - First Ember.js Model

in actions: {
saveInvitation() {

    this.set('responseMessage', "Thank you! We\'ve just saved your email address: ${this.get('emailAddress')}");   

display ${this.get('emailAddress')} in the page as full string

  Thank you! We've just saved your email address: ${this.get('emailAddress')}  

The address is save into the db..
