Abstract: We give details of the proof of the remark made in cite{G2} that the Chern characters of the canonical generators on the K homology of the quantum group $S{U}_q(2)$ are not invariant under the natural $S{U}_q(2)$ coaction. Furthermore, the conjecture made in cite{G2} about the nontriviality of the twisted Chern character coming from an odd equivariant spectral triple on $S{U}_q(2)$ is settled in the affirmative.
