If you want the actual books to be updated use "Wireless device connection/Sync newer book files". This makes calibre check the timestamp on the book in the calibre library and send it to CC if the book is newer than the one in CC. Go to Settings / Connecting to calibre then check the appropriate box. Uncheck the other Wireless device connection type if you want CC + calibre to always check the timestamp. For more info see our FAQ What does "Sync newer book files" (Settings / Connecting to calibre) do?

This cannot be the default for two reasons:

Checking the timestamp in calibre can be very slow, causing syncing to also be slow.
The calibre viewer can change the timestamp of a book. We don't want to download the book every time that happens

Also note that calibre does not store the fact that you changed the book, so it can't tell the difference between editing and replacing a book.
