Fix Timber - WordPress, ajax call

Attached are 3 files for reference. We are doing the following: -- using ajax to hit a function that will append are partial .twig file -- right now we can make the ajax call, but it only returns the basic HTML for 1 post, as opposed to the amount that should be returned -- finally, data is not getting appened to the .twig file through the function Does that make sense? Essentially we need what I believe is out function to fixed, so it appends the data correctly.
