Facebook's like button inside a JQuery Tools' tab
===

I have added Facebook's like button inside the first tab of a JQuery Tools' tabs.

When the page is loaded the first tab opens and Facebook's like button appears, this works as expected, but when you click on the second/third/... tab and then return to the first tab, Facebook's like button does not appear any more...

The following is what I added to the first tab for the addition of the like button:

    <div id="fb-root"></div>
    <script>(function(d, s, id) {
      var js, fjs = d.getElementsByTagName(s)[0];
      if (d.getElementById(id)) return;
      js = d.createElement(s); js.id = id;
      js.src = "http://connect.facebook.net/en_US/all.js#xfbml=1";
      fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));</script>

and placed the following code where I want the button to appear in the first tab:

    <div class="fb-like" data-href="http://www.mysite.com/example/thisPage" data-send="false" data-layout="box_count" data-width="60" data-show-faces="false"></div>

Any idea what's happening here, and how to reload the like button every time the first tab is loaded?
