Appending data does not work when it's child data

LaRichy

When I use this code

"columns": [
  { "data": "ssName2",
  fnCreatedCell: function (nTd, sData, oData, iRow, iCol) {
  $(nTd).append(' ('+oData['ss1Name2']+')'); }}
]

It works perfectly, but when I make the window smaller and the data goes to the responsive child rows, the append is gone.
Can you help me?

P.S. I am no developer!

Only, how to check if it isn't empty... See: https://www.datatables.net/forums/discussion/55863/append-only-if-there-is-data#latest
