How can I invoke the callback of an anchor using jQuery?

Jan,

A callback will always trigger a full page rendering. The callback mechanism works with a url in the anchor and therefore the browser expects a complete html page as a response.
Instead, try to do something along the lines of:

html anchor
       url: 'javascript:{}';
       onClick: (html jQuery ajax script: [ :s |
                       self doSomething;

                        s << (s jQuery: 'mydiv')
                                       html: [ :r | self renderMyDivOn: r ] ]) ;

       with: 'doit'.

Basically: include the action inside the ajax callback, right before invoking the rendering.
If you want to separate the blocks, you will need to use a callback: [...]; onComplete:[...] construction, I think.
Overriding of the url has proven necessary to me to avoid default browser behavior.
