Triggered after an Administration Area AJAX request is handled.
Note that if the AJAX request handler stops the script execution (by redirecting to another page, for example), the
backend:onAfterRemoteEvent event is not triggered. Example:
public function subscribeEvents()
{
Backend::$events->addEvent('backend:onAfterRemoteEvent', $this, 'after_remote_event');
}
public function after_remote_event($controller, $event)
{
traceLog('After '.$event);
}
