Closing doors (JavaScript)

I am attempting to close a door with JS, but can't seem to do it after attempting some lua->JS conversion. Anyone have an example?

Code:

var UpdateLayerMethod = global.BuildingBlock._type.GetMethod("UpdateLayer", rust.PrivateBindingFlag());
door.SetFlag(global.BaseEntity.Flags.Open, false);
UpdateLayerMethod.Invoke(door, null);
door.SendNetworkUpdateImmediate(false);
