Note that you set the timer timeout to be 5 second, but wait 3 second only.

You just change the timeout here. To restart the timer you have to
call timer.async_wait().
By the way, note that the timer is not threadsafe so I'm not sure it's
legal to restart it here or to change its timeout this way.
