title: Add and remove RealmChangeListener in View
body: <p>Is it a good idea to do this in a view that is going to be used in a <code>RecyclerView</code>?</p>
  
  <pre><code>@Override protected void onAttachedToWindow(){
      super.onAttachedToWindow();
      realmResult.addChangeListener(myChangeListener);
  }
  
  @Override protected void onDetachedFromWindow(){
      super.onDetachedFromWindow();
      realmResult.removeChangeListener(myChangeListener);
  }
  </code></pre>
  
  <p>what if the view is used outside a <code>RecyclerView</code> and is not recycled?</p>
