node-amqp exchange callback not being invoked

Question

I have the following code . My node version is v0.7.0-pre . When I run the code the screen prints

 Setup
 Completed setup

It does not print the Exchange Callback message . When I run the

rabbitmqctl --list_exchanges  

command I see the new exchange getting created but the callback is not getting called . I looked at the test cases and this does not seem to be a covered case . Let me know if this is a bug and if there is a work around

var util= require('util')
var amqp = require('amqp');

function setup() {
  console.log("Setup");
  var exchange = conn.exchange('cf1-demo',
    {'type': 'fanout', durable: false},
    function() {
    console.log("Exchange Callback");
 });
 console.log("Completed setup %s", exchange.name);
}
var conn = amqp.createConnection({host:'localhost',
                                    login:'guest',
                                    password:'guest'},
                             {defaultExchangeName: "cf1-demo"});
conn.on('ready',setup);

Answer 1

This was a problem with node-amqp being the old version . This seemed to be a problem with npm install as far as I can figure
