Backbone route not invoking an action with URL - asp.net-mvc

Question

This is the code to a simple ToDo app using ASP.NET MVC:
var Appointment = Backbone.Model.extend({
defaults: function () {
return {
'date': new Date(),
'cancelled': false,
'title': 'Checkup'
}
}
});
var AppointmentList = Backbone.Collection.extend({
model: Appointment,
url:"/Home/Appointments"
});
var AppointmentView = Backbone.View.extend({
template: _.template('<span class="<% if(cancelled) print("cancelled") %>"><%= title %></span>x'),
initialize: function () {
this.model.on('change', this.render, this);
},
render: function () {
this.$el.html(this.template(this.model.toJSON()));
return this;
}
});
var AppointmentListView = Backbone.View.extend({
initialize: function () {
this.collection.on('add', this.addOne, this);
this.collection.on('reset', this.render, this);
},
render: function () {
this.collection.forEach(this.addOne, this);
},
addOne: function (model) {
var appointmentView = new AppointmentView({ model: model });
appointmentView.render();
this.$el.append(appointmentView.el);
}
});
var AppRouter = new (Backbone.Router.extend({
routes: { "Home/Appointment/:id": "show", "": "index" },
initialize: function (options) {
this.appointmentList = new AppointmentList();
},
start: function () {
Backbone.history.start({ pushState: true });
},
index: function () {
var appointmentsView = new AppointmentListView({ collection: this.appointmentList });
appointmentsView.render();
$('body').html(appointmentsView.el);
this.appointmentList.fetch();
},
show: function (id) {
debugger;
var appointment = new Appointment({ id: id });
var appointmentView = new AppointmentView({ model: appointment });
appointmentView.render();
$('body').html(appointmentView.el);
appointment.fetch();
}
}));
$(function () { AppRouter.start() });
Please do not be overwhelmed by the code. If you look closely it is very simple as I am a noob.
My problem is that show action is not being hit. But index can works and can populate the page with view. I tried with all kinds of url to hit the show function but unsuccessful. Can someone please tell me what I need to do to make this right?
