title: Focusing a Bootstrap button for keyboard enter
body: <p>I have a Bootstrap 3.0 button on a web page.  The button is not part of a form.  When this page renders, I would like for the button to be clicked if the user hits return on the keyboard.  I have a Marionette event listener set up to handle the click event.</p>
  
  <p>Here is my button:</p>
  
  <pre><code>&lt;button class="btn btn-primary js-new pull-right"&gt;New facility&lt;/button&gt;
  </code></pre>
  
  <p>How do I do this?</p>
  
  <p>I have tried several things - including what I thought was the obvious solution: executing <code>$(".js-new").first().focus()</code>.  This does not work.</p>
