Do I need to remove event handlers from an element assigned by a custom directive in vue.js?

Question

Vue.js

I want to write a custom directive to install some event handlers. And I don't understand how to pass data between different directive life cycle hooks. Somehow I don't want to use Dataset at all. Accordingly, I don’t understand how and where I can save the identifiers of the handlers, so that later I can delete these handlers before unbinding the directive from the element. And is it necessary to remove these handlers at all? Will they go away on their own? In fact, I just need to hang up 2 handlers that cause user events and that's it.
