Stop bind -x command output from overwriting current prompt string

I have the following two bash aliases defined in .bash_aliases: # Better ls -al bind -x '"\el":"command ls -lAtr"' # Show newest 10 files in a folder bind -x '"\eh":"command ls -1U | head"' Now when I hit Alt+h or Alt+l to invoke the command, the command output overwrites the last shell prompt. This makes it hard to find where an ls starts and ends (if invoked multiple times). How can I stop it from doing that?
