title: Using raycaster method refreshObjects() in AFrame
body: <p>I am wondering how to use a method of a component in an entity
  for example.: I have the entity with a cursor and a raycaster component:</p>
  
  <pre><code>&lt;a-entity id=”raycaster_cursor" raycaster="objects: .clickable" cursor=”fuse .....
  </code></pre>
  
  <p>now i want to use the refreshObjects() Method of the raycaster component. How do i do that?
  Am I simply not understanding the concept of entities and components?</p>
  
  <p>I tried to do it like this:</p>
  
  <pre><code>var myCursor = document.querySelector(”#raycaster_cursor");
  myCursor.aycaster.refreshObjects();
  </code></pre>
  
  <p>and like this:</p>
  
  <pre><code>var myCursor = document.querySelector(”#raycaster_cursor");
  myCursor.components.raycaster.refreshObjects();
  </code></pre>
  
  <p>But thats not working.</p>
