Расширьте слайдер Emotion Banner Shopware

Мы пытаемся создать настраиваемый слайдер баннера для эмоций в Shopware. Этот настраиваемый баннер является производным от стандартного слайдера баннера эмоций и добавляет к нему несколько дополнительных столбцов. Все работает отлично и ошибок нет, однако модель полностью игнорируется, т.е. данные из сетки не сохраняются, поэтому событие добавления / сохранения не запускается. (Этот вопрос появляется здесь на немецком языке) Это наш компонент ExtJS:
