Well, data is saved onto an indexed cache. You can't have an empty
string as a key, you need a name for it. If you don't provide a name
you'll get back the internal ID of the selected element.
// from jQuery source, data.js ln 27
return name ?
jQuery.cache[ id ][ name ] :
id;
Any reason you need to use an empty string as a key?
