i get the same id

I've 3 div. each one has a different id, when i try to right-click on one of this div and then on another I get always the same id in the console log.
Why?

$("#container").children("div").mousedown(function(event) {
        switch (event.which) {
            case 3:
               // RIGHT CLICK
                console.log(this.id);
                break;
        }
    });
