Sail not syncing with Laravel Inertia

If i make a simple change to say routes/web.php, whilst running sail npm run dev, its not syncing with container. I did sail shell and looked into routes/web.php in container and its not reflecting my local changes. If i do sail down and then sail up -d it works, but again if i make another change its not syncing. I am using the default docker-compose.yml that comes with a sail install.
