We revisit the coupled-channel 
interactions and dynamically generate the resonances 
and 
within both the isospin and the physical bases. The – mixing effects are generated in the scattering amplitudes of the coupled channels with the physical basis, which exploits the important role of the channel in the dynamical nature of these resonances. With the scattering amplitudes obtained, we investigate the and contributions to the 
, 
and 
radiative decays through the final-state interactions. We obtain the corresponding branching fractions 
, 
, 
, and predict 
and 
. These fractions are within the upper limits of the experimental measurements.
