When you use .on('click', function (e) {}) function, it works only for existing elements. To handle click event on all selector elements, even for elements which will be added in future, you can use one of these functions:
$(document).on('click', "#appended", function (e) {
// some code code
alert('click!');
});
or:
$("body").delegate("#appended", "click", function () {
// your code goes here
alert('click!');
});

Instead of click function You can use :
1.live(old version)
2.delegate
3.on
But , if you want to use click with immutation of delegate function :
var myFn=function(e){
if(e.target.id=='apended'){
alert('click');
}
}
$(document).click(myFn)
