title: select2 from append not working
body: <p>I'm using the select2 plugin from <a href="http://ivaynberg.github.io/select2/" rel="nofollow">http://ivaynberg.github.io/select2/</a>.</p>
  
  <p>I've got a form where I can add a new line. What I do is get the html from the previous line and append it to my form.</p>
  
  <p>So this worked and the select2 is also added to the new line. The problem is when I click on the select 2 element nothing happened.</p>
  
  <p>Is there a way to solve this?</p>
