You need to use editable CellRenderers. So if you are packing a
CellRendererText for displaying the name, you do something like:

cell.Editable = true
cell.Edited += delegate (object o, EditedArgs e) {
	TreeIter iter;
	if (model.GetIter (out iter, new TreePath (e.Path))) {
		model.SetValue (iter, 1, e.NewText);
	}
}


If instead have some rich object you are storing in the TreeModel, and
you're modifying some field on it, you'll need to call
model.EmitRowChanged (iter, path); after updating it, to make sure the
rendering of the given row is updated accordingly.
