Backbone with underscore template example

I am new to backbonejs and underscorejs. I found some video materials on to watch and I faced problem when tried to modify example.

Here is my code:

<html>
<head >
    <meta charset="UTF-8">  
    <script type="text/javascript" src="javascript/jQuery.js"></script>
    <script type="text/javascript" src="javascript/underscore.js"></script>
    <script type="text/javascript" src="javascript/backbone.js"></script>

    <script type="text/template" id="list-template">
      <li><a href="<%= href %>"><%= text %></a></li>
    </script>

    <script type="text/javascript">


        model = new Backbone.Model({
            data: [
                {text: "Google", href: "google.com"},
                {text: "Facebook", href: "facebook.com"},
                {text: "Yahoo", href: "yahoo.com"}
            ]
        });


        var View = Backbone.View.extend({
            el: "#container",
            events: {
                "click button": "render"
            },
            render: function(){
                var data = this.model.get('data');
                for(var i = 0; i<data.length; i++){
                    var variables = { href: data[i].href, text: data[i].text };
                    var li = _.template( $("#list-template").html(), variables );
                    this.$el.find('ul').append(li);
                }
            }
        });

        var view = new View({ model: model });

    </script>
</head>

<body>
    <div id="container">
        <button>Load</button>
        <ul id="list">
    </ul>
    </div>
</body>

It of course does not work and I am failing to find the cause. If you see please answer or guide on how to bind template on custom event rather then initialize.

The problem is that the JavaScript is executing before the elements have been rendered on the page. Wrap your code in $(document).ready():

$(document).ready(function() {
    var model = new Backbone.Model({
    ....
    var view = new View({ model: model });
});
