Why is my Mongo query not working?

Question

I want to return some data from mongodb in a function. The body of the functions looks like this:

var name = '';
var ret = this.collection.findOne({"socket_id" : socket_id}).on('success', function(doc) {
    name = doc.name;
    console.log("name inside mongo callback is not empty" + name);
});
console.log("name here is empty" + name);

If I log the data in the console, the callback displays the data properly, but if I return form callback, I cannot seem to catch it from where I call the function. I suspect it has something to do with node.js being asynchronous and stuff, but how can I tackle this? Any help would be appreciated

@RabeeAbdelWahab but I am calling it synchronously as I am using monk as the database driver. I mean, it is asynchronous behind the scene I guess, but it should work that way I think — allisius, Oct 16 '15 at 12:35

So it turns out it was exactly because I was trying to get a synchronous response to an otherwise asynchronous functions. If you stumble upon this problem, I would refer you to the answer to this question:
