javascript - How to bind a function to Element loaded via Ajax

I have a couple of Divs in my page with CSS class="hello" Further I use Ajax to fetch a few more Divs with a CSS class="hello" I have a piece of code which is called on Click event of the Divs as follows:

$('.hello').click(function(){
  alert("Hello Clicked");
})

It works fine with the Divs that are present in my page from start but does not work with Divs loaded using Ajax. Is there something I need do in order to bind this little piece of code with the newly loaded Divs too?

you should use .on to bind the handler to another element that is already present during the execution of the binding, like say the <body>, or the document and have it detect the children events. but ideally, you should bind it to the nearest common parent of the content loaded.

demo

//bind to the body a "click" handler for elements that have class names of "hello"
$('body').on('click','.hello',function(){
  alert("Hello Clicked");
})
