I want a contact form

(function() {
  // Initializes callbacks container for the this specific scope.
  var callbacks = {};
 
  myApp.addContact = function(contact) {
    myApp.contacts.push(contact);
    callbacks[contact.id]();
  };
 
  myApp.registerContactCreatedCallback = function(contactId, callback) {
    callbacks[contactId] = callback;
  };
})();
