Duplicate values/wrong values in list

[mattharasim]

List values do not update properly when running the latest version of meteor, 1.2.1

This is still an issue even with Meteor 1.3.2.4, but it's not an issue with Meteor - it's an issue with the package. @day wrote a fix at: day/RubaXa-Sortable@cc483ad
