Asynchronous operations are handled in horizon as synchronous
operations. To illustrate that: launch an instance, you'll get
immediately a feedback ("launch instance issued").
But, you don't get a status feedback directly. Horizon pulls nova api
for status updates via ajax calls.
So: there is no solution yet for this. You could duplicate the same
update strategy as in launch instance (on instances page), create a
volume (on volumes table), etc.
In ideal case, one would use something like a message bus to get
notified on changes.
