Social Networking :: Google Plus One Is Not Showing On Particular Pages In Website

I have used Google Plus one in my web pages in my website. I have used this in a User Control Page and called this .ascx page into my all .aspx page. I have used the code like below: 

<g:plusone size="medium" width="120"></g:plusone>
<script type="text/javascript">
(function () {
var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true;
po.src = 'https://apis.google.com/js/plusone.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s);
})();
</script>

It is working fine in my pages except 2 pages in which it is not showing. When i see the view source of the page then i find the above javascript and HTML code. I have called 6 methods on the page load of these 2 pages. what is the reason of  Google Plus one not showing on my this 2 pages. what i will have to do to show  Google Plus one on my this 2 pages. I have called this User Control page on my other pages.
