Custom hooks and actions do not work with Infinite Scrolling

#### Steps to reproduce the issue

Hi there!

I'm using a custom-built child theme using Genesis as the parent theme. I have a template page `search.php` in my theme that gets used every time a user searches for something: www.mydomain.com/?s=something. In this page, I have custom hooks and filters that modify the display of my search page.

#### What I expected

All search results should display according to my hooks and filters.

#### What happened instead

When I use infinite scrolling, I noticed that the new posts load correctly; however, none of the hooks and filters inside `search.php` get triggered. So basically, half of the search results posts looks the way I want, and the other half (the ones loaded using infinite scrolling) does not.

I'm not using any search plugins.

Could you please provide me some guidance on this issue?

Thanks!

Hernán
