programmatically add annotation to google custom search

I was trying to add website dynamically in google custom search , so i add a xml file that pointing to my xml contains the website that is uploaded in a web space as it is mentioned in the google developer document underneath "Hosting the Annotations Files Yourself" like this

<GoogleCustomizations>
  <Include type="Annotations" href="http://ift.tt/14omjpn" />
</GoogleCustomizations>

but the website mentioned in the xml is not getting listed in the "Sites to search"

is there any way i could get the scenario done
