                url: "WebService.asmx/Like",
                data: "{ 'user': '" + user + "', 'article': '" + article + "' }",
                contentType: "application/json; charset=utf-8",
                dataType: "json",

                    if(msg.d ==  1)
                    {
                        $(".like[data-article='" + article + "']").fadeOut(700).addClass('unlike').removeClass('like').stop().text('Unlike').fadeIn(700);
                    }
                },
                failure: function (msg) {
                    alert(msg.d);
                }
            });
        });

$("a.unlike").on("click", function () {
            var article = $(this).attr('data-article');
            $.ajax({
                type: "POST",
                url: "WebService.asmx/Unlike",
                data: "{ 'user': '" + user + "', 'article': '" + article + "' }",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (msg) {
                    if(msg.d ==  1)
                    {
                        $(".unlike[data-article='" + article + "']").fadeOut(700).addClass('like').removeClass('unlike').stop().text('Like').fadeIn(700);
                    }

                },
                failure: function (msg) {
                    alert(msg.d);
                }
            });
        });
});

When I click on a link with class like it's working fine, the same when I click on a link with class unlike. However it doesn't working when I click the same link twice! When I'm searching on the internet, I see that I have to use live instead of click, however live was deprecated on 1.8 version. How can I make this fires multiple times?

Use jQuery.on():

$( document ).on( 'click', 'a.like', function () {
    // Do click stuff here
} );

You need to bind on to an element that will always be present. (document or some main wrapper div). Using on with the dynamic element will not work.
