title: Transform $(…).live in .on
body: <p>Today i checked my site for errors and i got this in Firebug console:</p>
  
  <blockquote>
    <p>TypeError: $(...).live is not a function</p>
  </blockquote>
  
  <p>for this code</p>
  
  <pre><code> $('#payment-address select[name=\'customer_group_id\']').live('change', function() {
          ......... SOME PHP CODE ....
      });
  </code></pre>
  
  <p>I've read <a href="https://stackoverflow.com/a/19110917/1773862">this</a> and the solution is to use on().
  But the problem is that i don't know javascript/jquery.</p>
  
  <p>Can anybody help me?</p>
