how to design 3-tier table relationship

Dear Sir,
I'd like to design a 3-tier table relation for customer.
for example:

TableA (parent): 
(
  id ,
  name,
)

TableB(child of TableA):
(
  id,
  TableA_id (from parent),
  id2
)

TableC(child of TableB)
(
  id,
  TableC_id (from id of TableB)
  name
)

I built successfully TableA and TableB relationship as our example
but failed to link TableC.

I got an error messge from data function listed below.

data: function ( d ) {
                var selected = TableB.row( { selected: true } );
                if ( selected.any() ) {
                    d.TableC_id = selected.data().id;
                }
            }

Because I used explicitly field expression,
TableB.id, TableC.TableC_id in my editor and table column,
How can I replace "id" in "selected.data().id" with the right expression?
(If I replaced "selected.data().id" with "selected.data().TableB.id",
I'll got a wrong expression warnning) .

Hope to hear the right answer here!

    Hi Allan,
    I've solved this issue already.
    I just replace the statement
    ''' d.tag_tagvalue_id = selected.data().id '''
    with
    ''' d['tag_tagvalue_id'] = selected.data().tag_tagvalue['id]'''
    Thank you!
