ASP.NET MVC calling server from javascript function with ajax

I am trying to call the following action method in a controller from a javascript function in a partial view:

[HttpPost]
    public JsonResult RemoveNotifications(IList<Notification> notifications)
    {
        Context.Notifications.RemoveRange(notifications);
        return new JsonResult();
    }

This is the function that should call the server from the view:

function show(message) {
    message += "</ul>"
    document.getElementById('notifications').innerHTML = message;
    $.ajax({
        url: '@Url.Action("RemoveNotifications", "Notification")',
        type: 'POST',
        data: { 'notifications': "@Model.Notifications" },
        contentType: "application/json; charset=utf-8",
        dataType: 'json',
        success: function (data) {
        }
    });
}

The first part works fine, but the $.ajax part dosen't do anything. I also have the following added at the top of my view:

<script src="http://ift.tt/1bhFrtf" type="text/javascript"></script>
<script src="http://ift.tt/1bhFrth" type="text/javascript"></script>
<script src="http://ift.tt/1bhFrtj" type="text/javascript"></script>
