CKEDITOR remove element event

Question

I using CKEDITOR for a text, and i want limited number of embed ( video and pictures ) who can upload a user, this mean need count there, problem is it I don't know who to count when a video or picture is delete white backspace. I was trying many way to catch event change and key but event key do not track when you press backspacing and remove a element. And with event change I do not see what element was removed or to make a comparation between actual data and previous data. I was try find who undo is implemented but I don't found.

If someone have any ideea who can track when remove a element please help me.

我在change和beforeCommandExec之间找到了一个组合，我计算了oembed类的数量和img标签的数量，我不知道这是否是最佳实践，但暂时仅是计算您的元素的可能性。
