these events are defined for MVCArray, a polyline is not a MVCArray. You must observe the events for the path of the polyline(which is a MVCArray) instead. Furthermore you can't add a listener to an object that isn't created yet. The polygon is not available before polygoncomplete, so you must add the listeners inside the polygoncomplete-callback:

google.maps.event.addListener(drawingManager,'polygoncomplete',function(polygon) {

  // complete functions

  google.maps.event.addListener(thePath, 'set_at', function() {
    // complete functions
  });

  google.maps.event.addListener(thePath, 'insert_at', function() {
    // complete functions
  });

});
