title: Can't set focus() on a text field
body: <p>This is just the weirdest thing. I've got a Sammy.js app, and I want to set focus on a text field right after the HTML loads. I've got this CoffeeScript here:</p>
  
  <pre><code>this.partial('templates/my-template.jqt').then -&gt;
    i = $('#item')
    debugger
    i.focus()
  </code></pre>
  
  <p>While I'm in the debugger, right on that line, I can inspect "i" and see that it's a JQuery object. I can even call i.val("HI THERE!") and see my text field update. But, calling i.focus() does absolutely nothing. Is there some security feature I'm missing that doesn't let you focus on a text element that was dynamically loaded?</p>
