The main reason is that the device is not managed by NetworkManager.
That's why enabling/disabling networking doesn't affect the device.

You should not have your interface defined in /etc/network/interfaces,
else it is not managed via NM.
For more info see 
man NetworkManager.conf, [ifupdown] plugin descriprtion
