You don't need to - you need to tell BIND to scan for new interfaces
periodically as per the BIND v9 Administrator's Reference Manual:

Alternatively, have all the VIPs on the loopback adapter so BIND can,
erm, bind to them; then when heartbeat brings up a VIP on the ethernet
interface, BIND is already listening and will pick up straight away.
