index mismatch after column is hidden in Datatable - datatable

Question

Hello I am using data table and as per some business logic certain columns in my table are shown or hidden for that I am sending the aoColumns as JSon from Java side, but the problem I am facing is in rowCallBack functions
I am manipulating columns on indexes which is miss-matched when I hide columns
This is how I am manipulating columns:
$('td:eq(0)', nRow).html(""+nameTrimmed+ "");
my guess is hidden columns are not counted in the index and rowCallBack just manipulates any column that is visible on that index
I can not write different rowCallBack for every case to keep it generic
Is there any way I can include the hidden column in index count?
or may be modify columns in some other way apart from indexes.
Here is the code
$('#myTable').DataTable({
