Callback on value change

[Rioni]

I'm trying to change node background depending on a variable, this makes things easier for me. But sadly I can't find a callback to hook, I'm currently using graph callback so if I click anything that is not a field it will be triggered

[CustomNodeEditor(typeof(RoomNode))]
public class RoomNodeEditor : NodeEditor
{
    private void Recolor(NodeController nodeController)
    {
        RoomNode room = nodeController.nodeItem.nodeData as RoomNode;
        nodeController.nodeView.style.backgroundColor = room.roomType switch
        {
            RoomNode.RoomType.Start => Color.green,
            RoomNode.RoomType.Hub => Color.white,
            RoomNode.RoomType.Normal => Color.gray,
            RoomNode.RoomType.MiniBoss => new Color(1, 0.682f, 0.125f),
            RoomNode.RoomType.Reward => Color.yellow,
            RoomNode.RoomType.Boss => Color.red,
            _ => throw new NotImplementedException(),
        };
    }

    public override void Initialize(NodeController nodeController)
    {
        Recolor(nodeController);

        //nodeController.graphController.graphView.OnAction += (action, obj) => { Recolor(nodeController); };
        nodeController.graphController.graphView.OnMouseDown += (mouseInput) => { Recolor(nodeController); };
        nodeController.graphController.graphView.OnAction += (action, obj) => { Recolor(nodeController); };
    }
}

It would be useful for this and similar features to have a callback for when any property of the node changes
