[Plugin Jetpack Infinite Scroll] – Not Working

Hi guys, 1st time trying to use the jetpack infinite scroll plugin, but even after I installed the plugin (and setup it to scroll infinitely on wordpress control panel), it keep not working, how do I set up the files? I tryed to follow the plugin docs, but I could not do this the correct way.
I even see any http request in my console, it’s a little weird, cause the plugin is installed. Maybe I messed up the things a little.

Here are my files, index.php, functions.php and content-produtos.php, please take a look at:
