how to get response body in restify after event?

I tried debugging/logging the response parameter in the function below but it doesn't contain the actual body.

function (request, response, route, error) {}

Above function was taken from restify documentation. Link below: http://mcavage.me/node-restify/#Server-API

Here's my code:

server.on('after', function(req, resp, route, error) {
    console.log(resp);
});

Thanks in advance!
