[jQuery] jQuery.data() woes

[Julie A]

How is jQuery.data() calculating the id?

I'm using code simar to:

$.fn.myPlugin = function() {
   return this.each(function() {
       console.log($.data($(this).parent().parent()));
       $(this).blur(function(e) {
           $.myPlugin.test($(this).parent().parent());
       });
   }
};

$.myPlugin = {
   test: function(target) {
       console.log($.data(target));
   }
}

And my console logs output different numbers for the same element
(I've triple checked in Firebug). Is this the GC kicking in or what am
I not seeing?

I'm using this to store options for my plugin based on instance. If
I'm totally misusing this, any ideas on what I could do to achieve the
same effect?

Thanks in anticipation!
