How to use Bootstrap scroll spy?

I cannot quite get the scroll spy to work properly with a vertical nav. Below you can find the code I use. For some reason, only "Two" gets active.

Anyone has an idea as of what is wrong?

<html lang="en">
<head>
    <meta charset="utf-8">
    <title>Twitter Bootstrap Scroll Spy Playground</title>
    <link href="bootstrap/css/bootstrap.css" rel="stylesheet">
  </head>
  <body>
    <div class="container">
      <div class="row">
        <div class="span3">
            <ul class="navbar nav nav-list affix">
              <li class="active"><a href="#one">One</a></li>
              <li><a href="#two">Two</a></li>
            </ul>
        </div>
        <div class="span1" data-spy="scroll">
            <section id="one">
            <h1>One</h1>
            <h2>Ad leggings keytar, brunch id art party dolor labore. Pitchfork yr enim lo-fi before they sold out qui. Tumblr farm-to-table bicycle rights whatever. </h2>
            </section>
            <section id="two">
            <h1>Two</h1>
           <h2>Anim keffiyeh carles cardigan. Velit seitan mcsweeney's photo booth 3 wolf moon irure. Nihil tattooed accusamus, cred irony biodiesel keffiyeh artisan ullamco consequat.</h2>
            </section>   
        </div>
      </div>
    </div>
    <script src="http://code.jquery.com/jquery-latest.js"></script>
    <script src="bootstrap/js/bootstrap.js"></script>
</body>
</html>

In sorting this out for myself, I've found that the element being spied upon needs to have a scroll bar.

Take a look at this Fiddle: http://jsfiddle.net/adamp/qgU6h/1/

You can either spy directly on the body element ($('body').scrollspy()) or give your content an explicit height and force it to show a scrollbar.

(If you look at the Bootstrap documentation example, it does the fixed-height trick.)
