Why isn't a function written to scope?

Question

Angular

I want to install a handler.
In the textbook so

Добавьте новый метод в контроллер PhoneDetailCtrl:

  $scope.hello = function(name) {
      alert('Привет, ' + (name || 'мир') + '!');
  }
и элемент:

  <button ng-click="hello('Elmo')">Привет</button>
в шаблон phone-details.html.

Moreover, the number and the string are written, but the function cannot be written, in scope
