With NodeJS modules, to make something public, you have to export it. Add this to the end of index.js:

module.exports.AddNumbers = AddNumbers;

Here it is running on my machine:

$ cat index.js 
function AddNumbers(a,b){
    return a+b;
}

module.exports.AddNumbers = AddNumbers;

$ cat example.js 
var index = require('./index');
var v2 = index.AddNumbers(5,6);
console.log(v2);

$ node example.js
