lightGallery in lightSlider - Slider.prepend() for 'onSliderLoad' is not working

Question

I have lightslider using lighGallery in the onSliderLoad. I have two set of code in my code snippet. jsfiddle

Code 1: Page load lightGallery view. I'm rendering image from HTML directly
Code 2: Button - ButtonClick_LightGallery - click lightGallery view. Rendering image through prepend.

My Issue: LightGallery is working fine in Code 1 but Code 2 is not working.

$(document).ready(function() {
  $('.demo').hide();
function BuildImageSlider() { 
  $('.demo').show();
  var slider = $('#lightSlider').lightSlider({
                gallery:false,
                item:1,
                loop:true,
                thumbItem:9,
                slideMargin:0,
                enableDrag: false,
                currentPagerPosition:'left',
                onSliderLoad: function(el) {
                    el.lightGallery({
                        selector: '#lightSlider .lslide'
                    });
                }   
            });  
            
            var newEl = '<li data-thumb="http://sachinchoolur.github.io/lightslider/img/thumb/cS-1.jpg" data-src="http://sachinchoolur.github.io/lightslider/img/cS-1.jpg">            <img src="http://sachinchoolur.github.io/lightslider/img/cS-1.jpg" />        </li><li data-thumb="http://sachinchoolur.github.io/lightslider/img/thumb/cS-2.jpg" data-src="http://sachinchoolur.github.io/lightslider/img/cS-1.jpg">            <img src="http://sachinchoolur.github.io/lightslider/img/cS-2.jpg" />';
            
         slider.prepend(newEl);
         slider.refresh();
           } 
  
  
  $('#lightSlider-pageload').lightSlider({
                gallery:true,
                item:1,
                loop:true,
                thumbItem:9,
                slideMargin:0,
                enableDrag: false,
                currentPagerPosition:'left',
                onSliderLoad: function(el) {
                    el.lightGallery({
                        selector: '#lightSlider-pageload .lslide'
                    });
                }   
            });  
            
      
  $( "#refresh" ).click(function() {   BuildImageSlider(); });
  
  });
