How to refer to a component using a directive?

Question

Angular

Let's say I have a directive clinging to the appMovable tag. I also have a window component, with code like this:

<div class='window'>
  <div appMovalbe></div>
  <div>{{ Content }}</div>
</div>

The appMovalbe directive is triggered on a click on an element. Sobsno the question itself: How in the function that processes the click in the directive to access the component and execute, for example, the function of the jUpdate component?
