title: included js file didn't run when loaded
body: <p>I include with this, my app on page's header:</p>
  
  <pre><code>&lt;script type="text/javascript" src="/bundle.js"&gt; &lt;/script&gt;
  </code></pre>
  
  <p>And browser load it, but didn't run.
  if I copy a response from server, and paste it to console it works fine. So.. what I do wrong?</p>
