It's a job for the package maintainer / package manager to take care of 
running update-desktop-database when a .desktop file contains a 
MimeType= line
And update-mime-database when /usr/share/mime file is installed
But you can run those too, just run them both, as root to 
/usr/share/applications and /usr/local/share/applications and possible 
as a user to ~/.local/share/applications, or whatever $XDG_DATA_DIRS 
paths you are using
Then if your kernel is properly configured to include INOTIFY support, 
and the system glib is compiled properly with a support for inotify, 
file changes are immediately picked up
