Backbone JS View Events not Firing?

I'm trying to play around with Backbone JS and so far everything seems to be making sense and working smoothly.

However with the code below, my custom events do not seem to be firing. Anything in the below code stand out as to why that might be? Do I need to "initialize" anything in the View? Any other pointers on the code/structure would be cool as well. Below is my full JS/HTML.

JS

var Todo = Backbone.Model.extend({});

var TodoCollection = Backbone.Collection.extend({

    model: Todo,
    url: '/Home/Todos'

});

var AppView = Backbone.View.extend({

    // where it should listen, required?
    el: $(".content"),

    events: {
        "keypress #new-todo": "enter"
    },

    initialize: function () {
        // _.bindAll(this, "render", "createOnEnter");
        // this.collection.bind("all", this.render);
    },

    hi: function () {
        alert('ohai');
    },

    render: function () {
        var lis = '';
        $.each(this.collection.models, function () {
            lis += '<li>' + this.get('Text') + '</li>';
        });
        $('#todo-list').append(lis);
        return this.el;
    },

    enter: function (e) {
        alert('hi');
    }

});


var TodoController = Backbone.Controller.extend({

    routes: {
        "": "todos"
    },

    initialize: function (options) { },

    todos: function () {
        var todolist = new TodoCollection();
        todolist.fetch({
            success: function (data) {
                var appview = new AppView({ collection: data });
                appview.render();
            }
        });
    }

});

$(function () {
    window.app = new TodoController();
    Backbone.history.start();
});

HTML

<div id="todoapp">
    <div class="content">
        <input id="new-todo" placeholder="What needs to be done?" type="text" />
        <div id="todos">
            <ul id="todo-list">
            </ul
