Playstation move upper knobs off?

I have a question about the glowing knobs on the playstation 4 move controller. This one ripped out of me and I can't get it on anymore. Please help

How should we be able to help? The way he went out, he'll have to go back in. Since the top plate is not divided, the ball will probably only be inserted into the hole above… It will be fiddly work, but there's no other way to do it during production…

I've tried it but it doesn't fit in anymore
