The final function does not get called because async.forEach requires that you call the callback function for every element.

Use something like this:

async.forEach(Object.keys(dataObj), function (item, callback){ 
    console.log(item); // print the key

    // tell async that that particular element of the iterator is done
    callback(); 

}, function(err) {
    console.log('iterating done');
});
