HTML input not updating value

I have a very strange problem (at least to me). I dynamically create textboxes, and it works fine. But the problem is when I try to write in those, if I check the html code, values that I write do not appear. I have no idea why this is happening or how to work arround this. Here is my code example.

<ul class="ml4 js-sortable-buttons list flex flex-column list-reset" data-disabled="false" id="page-content">
    <li class="p1 mb1 blue bg-white" id="id"><input type="text" class="textbox" /></li>
</ul>
<div class="center py2 ml4">
    <div class="js-add-textbox-button button blue bg-white" >add textbox</div>  
    <div class="show_html_button blue bg-white">show html</div>                     
</div>


<!-- <script src="../src/html.sortable.js"></script> -->
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> 
<script src="html.sortable.min.js"></script>
<script  type="text/javascript">
        sortable('.js-sortable-buttons', {
            forcePlaceholderSize: true,
            items: 'li',
            placeholderClass: 'border border-white mb1'

        });
        // buttons to add items and reload the list
        // separately to showcase issue without reload
        document.querySelector('.js-add-textbox-button').addEventListener('click', function () {
            doc = new DOMParser().parseFromString(`<li class="p1 mb1 blue bg-white"><input type="text" class="textbox"></li>`, "text/html").body.firstChild;
            document.querySelector('.js-sortable-buttons').appendChild(doc);
            sortable('.js-sortable-buttons');
            window.stop();
        });
</script>

    <script  type="text/javascript">
        $(".show_html_button").click(function () {
            var optionTexts = $("#page-content").clone(true);
            alert(optionTexts.html());
        });
</script>

Any help would be greatly appreciated.

That's not how javascript works. A webpage's HTML doesn't automatically update when an input field's value changes.

If you want such functionality, you could do this:

$(function(){
  $('.js-sortable-buttons').on('keyup change paste','input',function(){
    $(this).attr('value', $(this).val());
  });
});

You are missing reference to html5Sortable. https://cdnjs.com/libraries/html5sortable

        sortable('.js-sortable-buttons', {
            forcePlaceholderSize: true,
            items: 'li',
            placeholderClass: 'border border-white mb1'

        });
        // buttons to add items and reload the list
        // separately to showcase issue without reload
        document.querySelector('.js-add-textbox-button').addEventListener('click', function () {
            doc = new DOMParser().parseFromString(`<li class="p1 mb1 blue bg-white"><input type="text" class="textbox"></li>`, "text/html").body.firstChild;
            document.querySelector('.js-sortable-buttons').appendChild(doc);
            sortable('.js-sortable-buttons');
            window.stop();
        });

        $(".show_html_button").click(function () {
            var optionTexts = $("#page-content").clone(true);
            alert(optionTexts.html());
        });

    <li class="p1 mb1 blue bg-white" id="id"><input type="text" class="textbox" /></li>
</ul>
<div class="center py2 ml4">
    <div class="js-add-textbox-button button blue bg-white" >add textbox</div>  
    <div class="show_html_button blue bg-white">show html</div>
