Do you update the serial number in the zone file before you save the 
file?  

What you describe seems indicative of no update.  The serial must be 
bumped once per update.  This indicates that the zone has been changed 
and a reload is necessary.  After you save the zone file, execute a 
"rndc reload <zone>" to make named reload the zone.

Hope this helps.
