</html>As you have seen the problem is while attempting second time to display select field by giving value to '1st room child' select field so it is not working.
</div>
Your problem is something called "delegation." When you dynamically add something to the DOM that wasn't there when it was first loaded, you have to look through a pre-existing parent first.
Consider this. You have an existing element: <div id="loaded"></div>
Then, you dynamically add something in that div: <button type="button" id="someButton">
In order to get to listen for that click, you have to go through the parent div since it's an original part of the DOM.
$('#loaded').on('click', '#someButton', function () {
//do something
});
