onHoldCallsInProgress

Type: function()

Right after the user has selected a place, the browser will start a hold call to the seats.io servers. This call is asynchronous, and the browser will wait for the response.

onHoldCallsInProgress() gets fired just before the hold call starts. You should disable the 'next' button in your ticketing flow until onHoldCallsComplete() gets triggered (which means there are no hold calls in progress).

If a hold call is already in progress, and the user selects another place, we don't fire onHoldCallsInProgress() again. We only fire it once, when the first hold call starts.
