jQuery мобильная прокрутка вниз отключена после касания

Question

Ну, я использую Angularjs в качестве калькулятора для jquery мобильной страницы, и она прекрасно работает. Мысль, когда я автоматически нажимаю на пустую область фона, я попадаю в верхнюю часть страницы, полоса прокрутки отключается, и я нет доступа к области, где отображаются результаты. Вот мой код, какую ошибку я делаю ?? Большое спасибо заранее
