Custom improvement not adding resource to trade network

[Envisionred]

So I have a mod for Cuba in development, with some of the art and all of the code ready to go, except for one thing: I can build the hacienda (replaces plantation), and it shows up on the map, but it doesn't add the resource it's built on to the trade network.
The relevant code:
