Not able to connect a rabbitmq docker with appl docker - node.js

Question

I have a simple app (simple.js), written in nodejs,
var amqp = require('amqplib/callback_api');
amqp.connect('amqp://localhost', function(err, conn) {
conn.createChannel(function(err, ch) {
var q = 'hello';
ch.assertQueue(q, {durable: false});
// Note: on Node 6 Buffer.from(msg) should be used
ch.sendToQueue(q, new Buffer('Hello World!'));
console.log(" [x] Sent 'Hello World!'");
});
setTimeout(function() { conn.close(); process.exit(0) }, 500);
});
And I have dockerized it (simple-app). Then I pulled rabbitmq docker from docker hub.
When I try to link these in following manner :
docker run -d --name rabbitmq-server rabbitmq:latest
docker build -t simple-app .
docker run -d -P --name myapp --link rabbitmq-server:rabbitmq-server simple-app
docker logs a8789193af523b
I get the below mentioned error :
/usr/src/server/simple.js:3
conn.createChannel(function(err, ch) {
^
TypeError: Cannot read property 'createChannel' of undefined

I have tried many ways in order to resolve :
1. Exposed all ports with -P option using --links
2. Did mapping of specific ports with -p option --links
3. created network with bridge as driver and used that n/w for starting all my dockers.
None of the above methods seem to work, I am continuosly getting same error.
I am trying this on AWS (EC2) .. amazon linux.
Also, if I try to run the simple.js directly on linux, it is successfully connecting to my rabbitmq server (which is dockerized).
Please help me out here !!
