Bug Fix.

Bug fix for sorting columns in datatables in "iframe" format.
for eg:-
Sorting columns works for:
http://127.0.0.1:8000/eden/org/organisation.iframe/1/office
However doesn't work for,
http://127.0.0.1:8000/eden/org/organisation/1/office.iframe, due to incorrect Ajax call,i.e,
http://127.0.0.1:8000/eden/org/organisation.aadata/1/office.iframe...

Looks right to me, but the commit message says it doesn't work for all cases?
