Ajax using <g:remoteLink>

Reading through the Grails docs (see here Grails - Latest - #ajax), I was led to believe that I could use Ajax to update a div using the following syntax:

My view (Ajax/index.gsp)
<!doctype html>
<head>
<meta name="layout" content="main"/>
</head>
<body>
<div id="error"></div>
<div id="message"></div>
<g:remoteLink action="retrievePets" update="message">Ajax magic... Click here</g:remoteLink>
</body>
</html>

My controller (AjaxController):
package genericsite

class AjaxController {

def index() { }

def retrieveMessage() {
render "Weeee! Ajax!"
}
}

However, when I select the link, it just sends me to a page with "Weeee! Ajax!"

I know how to do this the typical jQuery way (which I'm pretty sure this technique essentially uses)... just wondered what I was doing wrong. Looks convenient.

You need to add

<r:require module="jquery"/>

to the <head> section of your GSP in order to load the javascript
library that makes <g:remoteLink> work.
