How to enable Q&A app on Google Hangouts on air

Question

Google Hangouts on air has useful application called Q&A.

It allows watchers to ask speakers with text questions and even vote on these questions. In user interface, you can enable this feature for certain event on your G+ page.

How do I enable Q&A session for Hangouts on Air programmatically? Currently in my project I launch Google Hangouts using the code described in docs here:

<script src="https://apis.google.com/js/platform.js" async defer></script>
<div id="placeholder-div5"></div>
<script>
  gapi.hangout.render('placeholder-div5', {
    'topic': 'cats',
    'render': 'createhangout',
    'hangout_type': 'onair',
    'initial_apps': [{'app_id' : '184219133185', 'start_data' : 'dQw4w9WgXcQ', 'app_type' : 'ROOM_APP' }],
    'widget_size': 72
  });
</script>

Then when I start broadcasting and try to launch Q&A app (clicking its icon at the left side of Hangouts window) it says "This feature is disabled".

Is there any way to do it?

Using the code snippet you provided, I managed to get Q&A working.

When you click the Q&A button, the toggle button changes from off to on for a short while, then flips back. I'm not sure why this is the case, but even though the button changed back to off, Q&A is still enabled. Just start the broadcast, and Q&A will be activated.
