Update Reverse DNS from dhclient

I am using the DDNS feature to update my dns server with host addresses. 
I would also like to be able to update the reverse look up at the same time.

This does not seem to work. I am able to achieve the same with the 
nsupdate tool, but I would prefer if this was done by dhclient.

Can I know what I am doing wrong ?

My config is as follows;

> key "nsupdate-key" {
>     algorithm hmac-md5;
>     secret "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
> };
> zone domain. {
>   primary;
>   key nsupdate-key;
> }
> zone 168.192.in-addr.arpa. {
>   primary;
>   key nsupdate-key;
> }
> send fqdn.fqdn "myhostname.domain";
> send fqdn.encoded on;
> send fqdn.server-update off;
> also request fqdn;
