finally, it works with Sven's solution but tag html has to be   as i can see
in the link class (initially it was <button> in my html).  
I create a ResourceLinkWithAnticache like this :
public class ResourceLinkWithAnticache<T> extends ResourceLink<T>
{
        public ResourceLinkWithAnticache(String id, IResource resource) {
                super(id, resource);
        }

        private static final long serialVersionUID = 1L;

        @Override
        protected void onComponentTag(ComponentTag tag) {
                super.onComponentTag(tag);
                String url = tag.getAttributes().getString("href");
                url = url + "&antiCache=" + System.currentTimeMillis();
                tag.put("href", url);                           
        }
}
