I don't see trim would be actually called in the demo. What am I missing?

@sarasura just change your helper a bit, you need something like this

<td>{{getNamesWithKomma CorrespondenceParties}}</td>

function getNamesWithKomma(names){
  return  names.map((i) => i.Name).join(', ');
}

live demo of it here
