The action property is only implemented for Button.js, which allows
you to create custom buttons quickly.

You are right, you should work with events here. In the case of
WfsGetFeatureInfo, the features will be queried and loaded into the
model you specified in the transactionResponseModel property (e.g.
"trm").
To do your action event-based, you should say
function myAction(objRef) {
window.alert("test");
}
config.objects["trm"].addListener("loadModel", myAction, config.objects["trm"]);
The third parameter of addListener is the context that will be passed
to the objRef parameter of the event handler. In your case, it might
be useful to pass the model itself, which will give you access to the
xml of the GetFeature response (objRef.doc).
Regards,
Andreas.
