javascript - Click event is not working for dynamically added button

I reffered Creating a div element in jQuery and creatd a div element using javascript. However when I added a button element dynamically, click is not working. What change do we need to do to make the button click working?

Note: We cannot move the function outside of document.ready due to kendo control requirements mentioned in Binding to multiple view models nested in the Dom

When you inject code into the DOM, the jQuery event handlers are not attached/bound to the new elements. (jQuery already did the bindings to DOM elements before the new code was injected). Therefore, when you click a button, no jQuery click event is trapped.

To attach event handlers (and thereby grab events from) injected elements, you must use jQuery .on(), as follows:

jsFiddle Demo

$(".statiscDIV").append('<div>FIRST</div>');
$(".statiscDIV").append('<div>hello <button class="MakeHoldDetailLinkButton">View</button>  </div>');

$(document).on('click','.MakeHoldDetailLinkButton',function(){
    showMakeAndHold();    
});

function showMakeAndHold() {

    alert("HIIIIIII");

}

The .on() method was added in jQuery 1.7 to replace bind(), .delegate(), and .live() -- it does the same thing as all of these. (To unbind event handlers from ANY DOM elements, use .off())
