It looks like back.js was created to replace the custom-js.js file used in the tutorials at wp.tutsplus.com but it looks like the bits relevant to repeatable fields weren't copied over.
Since custom-js.js isn't being queued anymore that means there's nothing to run when the repeatable field buttons get clicked.
