Replication update problem (no replies)

Hi all, I have a problem when using MySql workbench to update a replication.

I updated the master's schema (alert, create table actions) using workbench's "Synchronize Model", but the slave's didn't receive any change and got no error when I execute 'show slave status'.

However, everything works well when I executed the SQL statement through the command line.

It's that MySql workbench's synchronize statement will not write to binlog?

Please forgive my poor English...
