That is working for me. The problem I am having is that I am using 
someone else's javascript code that provides additional functionality if 
I give the <div> tag surrounding the repeatable element a  sequential 
ID. Since the auto_id doesn't affect the div tag, I need to grab the ID 
from an element and build a sequential ID from it.

My blockage is that nested_name only contains information if the 
repeatable is only one level deep.
For example:

type: Repeatable
nested_name:  outer
elements:
  type: Repeatable
  nested_name: inner
  elements:

If I grab the nested_name from the outer repeatable, I would get 
nested_name == outer_1
If I grab the inner nested_name, I would hope to get nested_name == 
outer_1.inner_1, but instead I get a NULL
