Angular - How can I remove from the DOM an element I have used $compile on?

What I need is the functionality of two ng-views. Because I can't I want to change the innerHTML of something and compile it. The problem I have is when I change the content again, I can compile, but does angular remove the binding on it's own, or I do I have to do it manually, if so, how?

EDIT: Explaining

I want to make a modal, whose content I can change and bind to different scopes (hence the $compile). But I don't want to destroy the whole modal, just some of its content, and change to another. My main doubt is if by removing some compiled HTML it can lead to memory leaks.

SOLVED

For this problem, I created a new child scope (with $new) and destroyed it whenever I changed the content. Thanks for everything
