Button in webapp single page


I use this code in my angular view:

<a class="twitter-share-button twit_" ng-href="https://twitter.com/intent/tweet?url={{socialLink_twi}}" data-counturl="{{socialLink}}">Tweet</a>
<script src="//platform.twitter.com/widgets.js"></script>

socialLink_twi is absolute url. The share work’s fine, but the counter in the button doesn’t increment.

I just have read the faq, my hosting supports HEAD request.

Have you ideas ?
