Alexa Node.js intent issue

I created an Alexa Skill using developer console. I added a new intent and added corresponding handler in NodeJS code. Launch request is working, but my Intent handler is not getting called. Please help.. what may be the issue ? For simplicity purpose, I'm pasting the basic code here..

JSON :

{
    "interactionModel": {
        "languageModel": {
            "invocationName": "intent test skill",
            "intents": [
                {
                    "name": "AMAZON.CancelIntent",
                    "samples": []
                },
                {
                    "name": "AMAZON.HelpIntent",
                    "samples": []
                },
                {
                    "name": "AMAZON.StopIntent",
                    "samples": []
                },
                {
                    "name": "HelloWorldIntent",
                    "slots": [],
                    "samples": [
                        "hello",
                        "how are you",
                        "say hi world",
                        "say hi",
                        "hi",
                        "say hello world",
                        "say hello"
                    ]
                },
                {
                    "name": "AMAZON.NavigateHomeIntent",
                    "samples": []
                },
                {
                    "name": "AMAZON.FallbackIntent",
                    "samples": []
                },
                {
                    "name": "helloworldtwo",
                    "slots": [],
                    "samples": [
                        "second intent",
                        "trigger second intent"
                    ]
                }
            ],

        }
    }

The shouldEndSession wasn't set to false, as I did not explicitly declare it or use the reprompt method in the response builder. That was the issue here :)
