How to re-initialize slideshow section after loading page via ajax?

I'm trying to do a super simple page load with ajax: 

$.ajax({
    url: 'https://subdomain.squarespace.com/somesspage,
    type:'GET',
    success: function(data){

        $('#container-to-load').html(data);
        var images = document.querySelectorAll('img[data-src]' );
        for (var i = 0; i < images.length; i++) {
           ImageLoader.load(images[i], {load: true});     
        }
    }
});

The issue is that slideshow section appears blank, only arrows appear: 

Is there a function / hack to make this type of sections work after loading via ajax?

As far as I'm aware, the latest version of Squarespace (7.1) doesn't allow for AJAX loading. Can you share you website URL?
