Ok, I found a solution on this site. Basically you override the afterFilter method with:

public function afterFilter() {
    parent::afterFilter();

    if (empty($this->request->query['callback']) || $this->response->type() != 'application/json') {
        return;
    }

    // jsonp response
    App::uses('Sanitize', 'Utility');
    $callbackFuncName = Sanitize::clean($this->request->query['callback']);
    $out = $this->response->body();
    $out = sprintf("%s(%s)", $callbackFuncName, $out);
    $this->response->body($out);
}

I hope it helps someone else as well.
