<script>
function myFunction() {
var x = document.getElementById("myBtn").value;
document.getElementById("demo").innerHTML = x;
}
</script>
<button class="btn btn-success" onclick="create_new_button()">Try it</button>
<script>
function create_new_button() {
var x = document.createElement("INPUT");
x.setAttribute("type", "button");
x.setAttribute("value", "Click me");
document.body.appendChild(x);
}
</script>
