How do I change the contents of a div inside a modal dialog using JQuery

I have the following jQuery dialog and I want to change the contents of a div inside the dialog just before I open it. However I can't seem to fathom it out, can any one help?

<div id="dialog" title="Basic dialog">
<div id="data"></div>

});

$("#data").html = "My new text"; /*THIS DOES NOT WORK*/
$("#dialog").dialog('open');

Thanks.
