Please define "code isn't working properly" in more detail.

One a side note, your code is relying on sequence point rules in a very
peculiar manner.  You do not actually violate any sequence point rule,
since the iterator arguments are passed by reference to iter_swap() and
there is a sequence point before every function call.  So what your code
does is basically the same as

  Gtk::TreeModel::iterator prev = iter;
  ListTreeModel->iter_swap(--prev, iter);
  iter = prev;

Don't know if this was intentional.  Anyway, it's probably unrelated to
the problem you were asking about.  It's hard to tell though since you
didn't say what the problem actually is.
