Reload nested datatables and open shown rows

Hey Everyone!
I have used nested datatables upto 2 levels. There is a datatable inside each row of which is another datatable inside each row of which there is another datatable. Data Source is ajax json. The question that I want to ask is how to update all the tables? ajax.reload closes all the rows on refresh.
Tried this

,the row opens but the datatable does not appear.

Any ideas as to what would work?

Thanks !
