I have set on fstab /home with 'mount bind' but it seems like bind is not effective.
Indeed. By default, nothing mounts "bind" filesystems. The init scripts don't read the hole fstab file, there are filters to mount only some filesystems types. If you want to mount the "bind" FS on boot, you need to add the related commands into /etc/rc.d/rc.local.
Nonsense! I'm also running CentOS 6.7 and have several bind-mounts in my /etc/fstab:
/var/home /home none bind 0 0 /var/lib/libvirt/etc /etc/libvirt none bind 0 0 /srv/news /var/spool/news none bind 0 0
All of them occur automatically when the system boots. The "mount -a" in /etc/rc.d/rc.sysinit takes care of them just fine. The filter on that command is _excluding_ certain types. Note that the first two letters are "no", which applies to all the listed types:
mount -a -n -t nonfs,nfs4,smbfs,ncpfs,cifs,gfs,gfs2i,glusterfs -O no_netdev
