Google button callback plus user share

Question

Is there a way to add a callback when a user shares something with custom sharing buttons?

I am currently opening a sharing dialog in a popup window:

<a data-height="600" data-title="Google+" class="popup" href="https://plus.google.com/share?url=MY_URL">Share</a> $('.popup').click(function(event) { var width = 575, height = $(this).data('height'), left = ($(window).width() - width) / 2, top = ($(window).height() - height) / 2, url = this.href, opts = 'status=1' + ',width=' + width + ',height=' + height + ',top=' + top + ',left=' + left; window.open(url, $(this).data('title'), opts); event.preventDefault(); }); 

In the documentation: https://developers.google.com/+/web/share/ they say that we can specify a callback using data-onendinteraction when using their js api. Unable to find a way to do this using a custom sharing link.

There seems to be no way to do this. There is an open question with this exact function request.

Take the lead and supporting it, but it has already been open for three years. It seems that Google is not trying to implement it.
