How you fix the problem depends on the design of your doorknob or lever and how it is fastened to the spindle and the door.
My lever handle fell off my front door.
If you are experiencing the lever falling off the set screw is still in the shaft.
That silver button is the set screw.
This screw fits in a groove on the round lever rod.
The exterior handle came off.
Try to leave the outside knob attached but if you can t that s okay.
If that escushion is smooth no screws in it there is probably a small set screw on the shank of the lever handle that holds it in place.
Looking at it there s a small hole in the lever and your first thought is that the set screw used to hold the lever in place came loose and fell off.
Sometimes the doorknob or lever loosens so it spins on its spindle while other times the lockset s mounting ring and faceplate become loose and pull away from the surface of the door.
There should be a tiny grub screw put in with an allen key it splays the split shaft spindle which grips the other handle my guess is its fell out.
The house door handle will continue to come off even after putting the handle back on.

Thanks for the suggestion but there s no hole for a grub screw anywhere on the handle or the shaft.
3 bring the spindle and knobs to the place and see if they have a knob that will fit your spindle properly and a screw to hold it in place.
If you remove the lever and on one side of the shaft there is a hole and the other side there is a silver button.
Place the lever back on to the shaft using a 3 32 hex wrench tighten the screw through the lever and shaft.
This would be confirmed by looking at the interior lever where there is a set screw that is screwed out from the shaft to hold the lever using the hole in the lever.
