How to add an export to a new created object through runtime.ToValue()

[al-sabr]

Having this function I would like to be able to add new private function from the newly create server object.

func (module *HttpModule) createServer(call goja.FunctionCall) goja.Value {

	if call.This != nil {

		if callee := call.Argument(0); !goja.IsUndefined(callee) {

			server := module.CreateServer(module)

			jsFn, ok := goja.AssertFunction(callee)
			if !ok {
				panic("The parameter passed doesn't contain a javascript function")
			}

			server.caller = jsFn

			toValue := module.runtime.ToValue(server)

			obj := toValue.ToObject(module.runtime)

			if obj != nil {
				err := obj.DefineAccessorProperty("listen", module.runtime.ToValue(server.listen), nil, goja.FLAG_TRUE, goja.FLAG_TRUE)
				if err != nil {
					panic(err)
				}
				toValue = module.runtime.ToValue(obj)
			}

			return toValue
		}
	}

	return nil
}

I would like to be able to add a new function to the converted object and then recreate a runtime.toValue(obj)

Is this possible with the current goja API?
