This is quite different, bat it should be esealy adapted to your case:

  cell = gtk_cell_renderer_toggle_new ();
                
  /* both model pointer and widget reference are sent
   * to item-toggled callback function, packed in a
   * ModelAndWidget (custom) structure
   */
  mw = (ModelAndWidget *)g_malloc (sizeof (ModelAndWidget));
  mw->model  = model;
  mw->widget = drGraph;
  g_signal_connect (cell,
                    "toggled",
                    G_CALLBACK (on_tvCurves_item_toggled),
                    mw);

  col  = gtk_tree_view_column_new_with_attributes ("Selection",
                                                   cell,
                                                   "active",
                                                   0,
                                                   "activatable",
                                                   2,
                                                   NULL);
  /* adding columns to TreeView
   */
  gtk_tree_view_append_column (GTK_TREE_VIEW (treev), col);


Information attached to toggles in a treeview are packed into a custom 
structure and retrievd when they are toggled.
