There are many reasons why a client might not get a lease straight
away, but usually the logs will show why. By now you should be
familiar with the Discover-Offer-Request-Ack cycle of messages, so
you are looking for log entries that are different to this.

As Glenn says, see the config examples. You can allow updates by IP
address, but normally you would use a key to sign updates, and for
this you need zone declarations in your DHCP config (which I see you
don't have). The default for BIND is to not allow any updates, so any
attempts will fail. Again, the logs are your friend - both the DHCP
server and the BIND server.
