slideshow is not showing in a post call with ajax

When you load a page that contains a normal static post, there is some JavaScript that is called on page load to instantiate your slider. Something like:

jQuery(document).ready(function($){
    $('.sliders').someSliderScript();
});

This finds all of the elements that should have a slider applied and runs all the necessary code to set it up and make it all work.

When you load content via AJAX, that code has already run and won’t automagically apply the slider to your newly loaded content. After your AJAX content is added to the page, any JavaScript manipulation of that content has to be called again.
