Percona XtraDB Cluster and MySQL Replication

Question

I've setup a 3-node multi master replication with percona xtradb cluster, it works perfectly.

Now I've tried to add some read-only slaves setting up replication as usual but it seems the binlog doesn't include the new inserts,

I've set binlog_do_db on the master of a database, slave says the log position is the same as the master ones but the new data isn't there.

Is there a special way to do replication on xtradb cluster?
