Javascript doesn't work when loading popover with button click event

Question

Yosh! In a popover, I added two links. The 1st refers to an action by the controller (And it works) The second contains a simple class, which, when clicked, should trigger launch a simple alert in JS. Except it doesn't work.

The popover header code in the DOM:

$(".show").click(function(){

var header = "<a class='btn btn-sm btn-primary js-alert'>Click on me</a>";
 $(".show").popover({
    title: header,
    placement: 'top',
    trigger: 'click',
    content: "toto",
    container: 'body',
    html: true
 }).popover('show');
});

$(".js-alert").click(function(){
 alert("Hello !");
})

    <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>

    <div class="container mt-4">
  <button type="button" class="btn btn-secondary show">Show popover</button>
</div>

And when I click on the second link, nothing happens at all (and no error)

This is an example on jsfiddle : https://jsfiddle.net/kiuega/ec3v1mfn/
