Problem With jQuery AppendTo and Data Attributes

[AnalogNerd]

I've run into a rather interesting, and frustrating bug that I'm hoping someone has some experience with or can help me work around. Here's the scenario, and I've also set up a fiddle to show it [^] I have a div with data-location="1" If I move this div like this

$("#myDiv").appendTo("#someOtherDiv");

and then change the data-location value

$("#myDiv").data("location", "newValue");

I can no longer find the element using the data-location attribute. This returns 0

$("[data-location='newValue']").length;

This returns 1

$("[data-location='oldValue']").length;

BUT, this returns newValue

$("#myDiv").data("location");

Has anyone ever run into this? Am I missing something here, or doing something wrong? [EDIT: has some trouble with the fiddle, the link works now.] [EDIT: SOLVED] Apparently the .data in jquery only reads the attributes once and never sets the attributes. If you want to set data- attributes and recall them in your code you have to use the .attr() call.
