RSS Reader - refresh the Feeds list?

Question

I'm using the Spry RSS example. I want to refresh the Feeds
list (on the left side of the page) every 5 seconds. I've added the
following line...
dsCategories.startLoadInterval(5000); // Start loading data
every 5 seconds.
I can see the browser making the data call every 5 seconds,
however the Feeds list on the page doesn't update. Any
ideas?

I've tried chaining the data sets and it still doesn't work.
When the page first loads, I see the GET to
"/getFeedList?alert=dsFeeds". However, when I call
dsFeeds.loadData() I never see the HTTP request taking place. I
should see the GET to "/getFeedList?alert=dsFeeds" again, but I
never do.
Here's my code...
var d = new Date();
var dsFeeds = new
Spry.Data.XMLDataSet("../getFeedList?alert=dsFeeds&cachebuster="
+ d.getTime() , "Feeds/Feed", { sortOnLoad: "Label" , useCace:
false });
var dsCategories = new Spry.Data.XMLDataSet(null ,
"Feeds/Feed/Category", { distinctOnLoad: true, sortOnLoad:
"Category", useCache: false });
var dsChannel = new
Spry.Data.XMLDataSet("../getRSS?id={dsFeeds::Handle}&alert=dsChannel&cachebuster="
+ d.getTime() , "//channel" , { useCache: false });
var dsArticles = new
Spry.Data.XMLDataSet("../getRSS?id={dsFeeds::Handle}&alert=dsArticles&cachebuster="
+ d.getTime() , "//item" , { sortOnLoad: "pubDate" ,
sortOrderOnLoad: "descending" , useCache: false });
dsArticles.setColumnType("pubDate", "date");
function updateCategories(notificationType, notifier, data)
if (notificationType != "onPostLoad")
return;
var doc = dsFeeds.getDocument();
if (doc)
dsCategories.setDataFromDoc(doc);
dsFeeds.addObserver(updateCategories);
setTimeout(function() { dsFeeds.loadData(); }, 5000);
