@chris1984 is going to give this a quick test, stand by :)

This part can be achieved by adding title to Modal.

The tests looked good to me. Power state was updated correctly on the host index page.

Sometimes I noticed each host was called for power state twice. And sometimes only some hosts got called for power state twice.
And I think each host should be called only once for power state after the power change.
Not sure what is exactly going on here. Maybe it is expected.

Tested and working good as far as turning on and off the hosts. I did notice what @lfu mentioned as well with it being called twice.
