Backbone model is not rendering default? Need Jade and Backbone gurus

Hey so I am having a problem where my templates change but the backbone model does not seem to provide the info I need. I am trying to solve this so I can move on to making collections. I am not getting any errors and I am using handlebars but have tried underscore's templating as well and the problem doesn't lie there but against the info displaying. When I click edit and the edit template shows it is showing undefined for #{firstName} and the others.

Main.js file

(function () {
    window.App = {
        Models: {},
        Collections: {},
        Views: {},
        Templates: {},
        Router: {}

    };

    // MODEL
    App.Models.User = Backbone.Model.extend({
        defaults: {
            firstName: 'first',
            lastName: 'last',
            email: 'Email',
            phone: '222',
            birthday: 'date'
        },

        validate: function (attrs) {
            if (!attrs.firstName) {
                return 'You must enter a real first name.';
            }
            if (!attrs.lastName) {
                return 'You must enter a real last name.';
            }
            if (attrs.email.length < 5) {
                return 'You must enter a real email.';
            }
            if (attrs.phone.length < 10 && attrs.phone === int) {
                return 'You must enter a real phone number, if you did please remove the dash and spaces.';
            }
            if (attrs.city.length < 2) {
                return 'You must enter a real city.';
            }
        },

        initialize: function() {
             this.on('invalid', function (model, invalid) {
                console.log(invalid);
            });
        }

    });


    //VIEW
    App.Views.User = Backbone.View.extend({
        el: '#user',
        //model: userModel,
        //tagName: 'div',
        //id: 'user',
        //className: 'userProfile',
        //template: _.template($("#userTemplate").html()),
        //editTemplate: _.template($("#userEditTemplate").html()),


        initialize: function (){

        },


    render: function() {
        this.template = Handlebars.compile($("#userTemplate").html());
        this.editTemplate = Handlebars.compile($("#userEditTemplate").html());

        this.$el.html(this.template(this.model.toJSON()));
        return this;
    },

    events: {
        'click button.edit': 'editProfile',
    //  'click button.save': 'saveEdits',
        'click button.cancel': 'cancelEdits'
    },

    editProfile: function () {
        this.$el.html(this.editTemplate(this.model.toJSON()));

    }, 

        //saveEdits: function (e) {
        //  e.preventDefault();

        //  var formData = {},
        //      prev = this.model.previousAttributes();
//

            //get form data
        //  $(e.target).closest('form').find(':input').not('button').each(function(){
        //      var el = $(this);
        //      formData[el.attr('class')] = el.val();
        //  });

            //update model
        //  this.model.set(formData);

            //render view
        //  this.render();

            //update array
        //},

        cancelEdits: function() {
            this.render();
        }

    });
    //start history service
    Backbone.history.start();

    var user = new App.Views.User({model: new App.Models.User()});
    user.render();
})();
