Hi Marc,
I have implemented as per your suggestion.
For now i am using bartik theme and new drupal installation to test the feature.
After performing all the steps, still i am not getting infinite scroll and even i don't get any error in firebug also.
All javascripts are seamlessly integrated but it is not working yet.
There is no error in firebug too.
