In short, MX record needs to continue pointing to your onpremise IP. This will take care of the inbound emails from internet.
For Outbound mails to be routed through onpremise, you need to enable "Centralized Mail Transport" while re-running hybrid configuration wizard. This will ensure that outbound emails to internet from Office365 as well as ONpremise will get routed through the onpremise gateways.
