moh.computer@yahoo.com

I think this is repeated question, but i see all answers and nothing clear ?
I used datatables in my MVC app and everything work perfectly , till i add new row to this datatable using
table.api().row.add after that i assigned row id using two methods then draw
1- row.nodes().to$().attr('id', ID)
2- row.node().id = ID
When i try to get the new added row id using row.id its undefined and row.data not contain dt_rowid at all.
In html i can see the id correctly added
How to get the id for the new added row
Please help me
