  In this note, we extend our previous work [Phys. Lett. B 644, 7 (2007),
astro-ph/0609597], and compare eleven interacting dark energy models with
different couplings to the observational $H(z)$ data. However, none of these
models is better than the simplest $\Lambda$CDM model. This implies that either
more exotic couplings are needed in the cosmological models with interaction
between dark energy and dust matter, or {\em there is no interaction at all}.
We consider that this result is disadvantageous to the interacting dark energy
models studied extensively in the literature.
