This is because the second argument to the model's data() method specifies
the role, not the column number.

You need to pass an index with the correct column number to the model's
data() method. One way to do this is to call the index's sibling() method
with the column number you want, then pass this to the model's data()
method. Maybe something like this:

  index = n.sibling(n.row(), 0)
  print QtCore.QVariant.toString(mo.data(index))

Hope this helps,
