Dandrobium with roots growing near the top of the cane

[Judi]

I have a dandrobium propagation question. I have a D. Jairak dendrobiun which is not doing well, it has few good roots in the pot, is ~ 10 inches high with 3 canes. Two canes are plump, one has no leaves, the other has two babies with ~ 4 leaves and ~ 5 1/2 inch roots for each at the top of the cane. The third cane is skinny with a ball at the top. Can I save the chid by planting the babies? Could I do it now or later, how do I do it ? I last repotted it 2 months ago after trimming the dead roots, but it didn't seem to work. Please help!
