Node.js Cannot read property 'on' of undefined
<p>What is wrong?</p>

<p>p.s. : I am new to node.js and I'm from .Net world!</p>

<p>My server.js code :  </p>

<pre><code>    var events = require('events').EventEmitter;
    var v = function() {
        var e = new events();
        e.emit('start');
    };

    var r = v();
    r.on('start', function(){
        console.log('event start just fired!!!!!!!!!!');
    });
</code></pre>

<p>and this console output :</p>
