[jQuery] using .live() with Beauty Tip - is it possible?

I'm using Beauty tip http://www.lullabot.com/files/bt/bt-latest/DEMO/index.html
for example such as:

$('.myclass').bt({
content: 'test content'
});

which displays a nice tooltip.
But how can I use it with jQuerys live event so that dynamically added
classes will also work with the tip?
I can't get the syntax working. Thanks.
