Inspector changes do not update data correctly (Angular)

GoJS

Here is a repo that reproduces this problem: https://github.com/Hazzed5/gojs-inspector-example

Text present in the node is a subproperty and is bound by this function:

const makeTwoWaySubBinding = (
      targetname,
      sourcename,
      conversion?,
      backconversion?
    ) => {
      const bind = new go.Binding(targetname, "message");
      bind.mode = go.Binding.TwoWay;
      bind.converter = (message, target) => {
        const value = message[sourcename];
        if (value === undefined) return target[targetname];
        return typeof conversion === "function"
          ? conversion(value, target)
          : value;
      };
      bind.backConverter = (value, data, model) => {
        const message = data.message;
        if (model)
          model.setDataProperty(
            message,
            sourcename,
            typeof backconversion === "function"
              ? backconversion(value, message, model)
              : value
          );
        else
          message[sourcename] =
            typeof backconversion === "function"
              ? backconversion(value, message, model)
              : value;
        return message;
      };
      return bind;
    };

Maybe that’s the issue?
