Ajax specific template not loading in replacement of index.php

There is no is_home_page() function in Core. You have either is_home() or is_front_page() and you have to be careful about the two. They can be squirrelly.

I don’t know which of the two functions you need but sorting that out should solve the problem, or use (is_home() || is_front_page()) perhaps.
