title: How to catch delete and download events in File Download component?
body: <ol>
  <li><p>I need to somehow catch an event when user deletes an attachment in File Download component (bin icon). I'd like to autosave document or at least tell him, that document has been modified and he must save it.
  User deletes attachment and closes a window and attachment remains undeleted. User doesn't know it, he thinks, that attachment is gone, while it disappears from the attachment list.</p></li>
  <li><p>I need to somehow catch an event when user downloads a file. I want it to be added to a log.
  Something like: 1.1.2014 12:33 Johnny Cash downloaded four-roses.pdf</p></li>
  </ol>
  
  <p>Any solution?
  Thanks, JiKra</p>
