i have tried your code but it worked for me.the difference is that you need to pass data in correct format. data:data or data:{ data:data } but not data:{data}

     function button_click() {
        $.ajax({
            type: 'POST',
            url: 'Demo/Demo_action',
            data: { data: "what you want to pass" },
            //dataType: 'json',
            //contentType: 'application/json',
            success: function (data) {
                if (data == "hello") {
                    call(data);
                }
            }
        });
    }
    function call(data) {
        var ans = confirm(data)
        if (ans) {
            $.ajax({
                type: 'POST',
                url: '@(Url.Action("Demo_action2", new { Area = "Mec", Controller = "Home" }))',
                //url: 'Home/Demo_action2', // this url not goes to the controller
                data: { data: data },
                dataType: 'json',
                success: function (data) {
                    alert(data);
                }
            });
        }
        else
        { }
    }
