Выпадающий список Django не работает при нажатии кнопки отправки

У меня есть раскрывающийся список и кнопка «Отправить» на странице. Некоторые поля исчезают при выборе определенного раскрывающегося списка. Я могу скрыть / показать все остальные поля, кроме поля пароля. Всякий раз, когда я скрываю поле пароля с помощью jquery, кнопка отправки не работает. Ниже приведены мои файлы кода.

1. HTML шаблон django

< script >

  $(document).ready(function() {


    $('#type').change(function(eventObject) {
      if ($(this).val() == 'sercomm') {

        $('.sample').show();
        $('.sample_netip').show();
        $('.sample_password').show();
        $('.sample_username').hide();

      } else {
        $('.sample').show();
        $('.sample_password').show();
        $('.sample_netip').hide();

      }
    }).change();

  });

Forms.py идет сюда

views.py (только кнопка create (post) дает:

            if 'create' in request.POST:
            form = BaseStationDetailsForm(request.POST)
            if form.is_valid():

                    errors.append(msg)
                else:
                    _type = request.POST.get('type', '')

                    basestation = BaseStation(name=data['name'],

                    # test
                    basestation.save()

                    return HttpResponseRedirect(request.get_full_path())
            else:
                for error_key in form.errors:
                    for error_msg in form.errors[error_key]:
                        errors.append(error_msg)

### other post button functions code deleted

return render_to_response('basestations.html', locals(), context_instance=RequestContext(request))

Пример - я могу показать / скрыть имя пользователя / описание, кнопка создания работает. Только когда поле пароля скрыто, кнопка не работает.
