У меня есть полный календарь на моей странице, и всякий раз, когда я перетаскиваю событие из Draggable Events на дату календаря и ОБНОВЛЯЮ/ПОВТОРЯЮ страницу, перетаскиваемое событие исчезает. 
Как сделать так, чтобы вновь созданное и перетаскиваемое событие оставалось на месте всякий раз, когда я обновляю или перезагружаю страницу? Я все еще впервые использую Полный Календарь, поэтому я еще не знаком с ним.
Вот мой исходный код:

Надеюсь, кто-нибудь может помочь.
