Simple map function call in nodejs async library not working

Question

Recently I discovered async library and wanted to try it. The information provided for getting started is quite simple. So I decided to try an example. I tried it, the call reaches the iterator function but never reaches the callback. Could someone advise?

var async = require('async')

// My simple iterator
function foo(item){
    console.log('foo');
    return item;
}

// And this is my simple try out
async.mapLimit(inputData,100,foo,function(err, result){
    console.log(err, result, 'Finished');
});

@caolan, Please advise....

foo should be

function foo(item, callback){
   console.log('foo');
   callback(null, item); // or actually do something to item
}
