I'm trying to get the twitter on page tabbed content to work. I have the tabs working with switching around active class on the tabs. I've included jquery and the bootstrap-tabs.js but the following code can't seem to get the tabbed content to hide / display as they should. Any help on what may be a simple fix would be appreciated.

<div class="span8">
        <ul class="tabs" data-tabs="tabs">
            <li class="active"><a href="#2009">2009</a></li>
            <li><a href="#2010">2010</a></li>
            <li><a href="#2011">2011</a></li>
        </ul>
        <div class="pill-content">
            <div class="active" id="2009">
                2009 copy
            </div>
            <div id="2010">
                2010 copy
            </div>
            <div id="2011">
                2011 copy
            </div>

        </div>
        <script>
        $(function () {
            $('.tabs').tabs()
        })
        </script>
    </div><!-- end span 8 -->
