Where should I put the code to change class of the parent element in Angular?

Question

I am building a plugin to a larger application that uses Angular.
The plugin is basically an include in a larger HTML document.

I want to change class of the plugin's parent element.

I can't change parent HTML directly, so where should I put the code to do addClass ?

Directive feels like an overkill (and it would either be very specific, or I would have to re-implement whole ng-class ). But it might be a fair answer.

I think directive is a way to do it. From Angular's documentation:

Manipulate DOM — Controllers should contain only business logic. Putting any presentation logic into Controllers significantly affects its testability. Angular has databinding for most cases and directives to encapsulate manual DOM manipulation.
