data() does not look for an actual "data" attribute string value on
the DOM.
You have to set it with data(), like:
$("#myElement").data('name', 'foo-bar');
and get it with:
$("#myElement").data('name');
The second argument (value) is not limited to a string. You can use
objects, etc.

Additionally, "2009-08-2816C213" is not a valid class name. Class
names cannot begin with a number.
