title: fire a "paste" event in Javascript
body: <p>I know this topic discussed many times.
  But this one a bit different.
  I need to "dispatch" a "paste" event (like after copy "paste").</p>
  
  <p>Why do I need that ? 
  Well when you copying a link into a message textarea in Facebook,you see that automatically ajax script called that alters the page so that recipient could see attached image besides the link.</p>
  
  <p>since I'm not going to use Facebook API's and stuff,I just want to call the paste event that hopefully will trigger the script that I need.</p>
