Something like this will do the job:

$ PROMPT_COMMAND="history -w; $PROMPT_COMMAND"

It will not overwrite your current $PROMPT_COMMAND and make Bash
append current history to $HISTFILE after every command execution and
not only when a shell exits.

BTW, be aware of difference between login and non-login shells.  When
you log in for an interactive session in tty ~/.bashrc is not read and
the above should be added to ~/.profile.
