That is incorrect usage of ​.serialize() and invalid html (​http://dev.w3.org/html5/spec/global-attributes.html#embedding-custom-non-visible-data-with-the-data-attributes). Please ask for support on the ​forums or on the #jquery irc channel.

$('input[zcodeg="inner"]').each(function(){
  alert($(this).attr('name'));
});

Is invalid?
