My callback "onPlus" on Google+1 button from external website does not work anymore after the latest update of Google of removing the counts on Google+1 button.
See https://plus.google.com/110610523830483756510/posts/Z1FfzduveUo
My Code
<script src="https://apis.google.com/js/platform.js" async defer></script>
<div class="g-plusone" data-href="http://sample.com/" data-autoclose="true" data-recommendations="false" data-callback="onPlus"></div>
Is there any way to bring back the callback feature?
