title: Datepicker from and to startDate not working
body: <p>Date pick "from" and "to" work for the first time, but when I change the date "from", the date "to" is not working.</p>
  
  <pre><code>&lt;script src="js/jquery.min.js"&gt;&lt;/script&gt;
  &lt;script src="js/bootstrap.min.js"&gt;&lt;/script&gt;
  &lt;script src="js/bootstrap-datepicker.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>HTML</p>
  
  <pre><code>&lt;th&gt;From: &lt;input type="text" class="from span2" value="" id="from"&gt;&lt;/th&gt;
  &lt;th&gt;To: &lt;input type="text" class="to span2" value="" id="to"&gt;&lt;/th&gt;
  </code></pre>
  
  <p>Script</p>
  
  <pre><code>var from = $('.from').datepicker({autoclose: true}).on('changeDate', function(e){           
  
      $('.to').datepicker({autoclose: true, startDate: e.date })
  
  });      
  </code></pre>
  
  <p>Here's my code <a href="http://jsfiddle.net/britonet/VS2zS/2/" rel="nofollow">http://jsfiddle.net/britonet/VS2zS/2/</a>
  First try it works perfect, I choose FROM = 07/03/2013, and Date TO disabled 07/02/2013, 07/01/2013.. and so on... but again if i change date FROM = 06/10/2013, it did not disabled Date TO</p>
