Repeating Table and Auto Numbering

Hi All, 

Trying to create an auto populated table. I've gotten the table number to auto number (1,2,3 etc), however I have another cell within the table that needs to auto populate too. I can get that done in the first table, but when another table is added the cell continues numbering instead of starting at 1 again (screen shot below). 

Help? in the cell I want to restart numbering I have the this.rawValue = this.parent.index +1; formula. The header where it says the goal number also has this.

This is what the hierarchy looks like:

Body row is the Goal heading 

and Objective is the row I'm having trouble with restarting the numbering when I repopulate (add a new instance) of the entire table.

This is what the binding looks like:

Any help would be greatly appreciated!!
