I created the wrapAll Function, but for some reason some scripts refuse to work with references to elements that have been changed, why?

Question

JavaScript

I created the wrapAll Function, it creates a tag and throws the necessary elements into it (appendChild), thereby creating a wrapper, and the old elements are deleted. And everything would be fine, but for some reason the scripts stop working. (For example, when you click on submitting the form (ajax), it is not sent, although without wrapAll it works fine).

Answer 1

for some reason scripts stop working

Suddenly, because the elements on which the handlers were set were removed. Show full code.
