setLatLngs not working

I try to update geometry already drawn on the map. but seems no error but it's not updating why?
```
 var layer = this.getMapObject(id);
  layer.setLatLngs([[144.32965127509, -38.135825028205],[144.32972099984, -38.135581614469],[144.3305381716, -38.135726427806],[ 144.33046844684, -38.135969841054]]);
  layer.transform.reset();
```
