Is unbinding callback necessary before deleting socket?

I have memory leak in my js multiplayer game. I bind a lot of callbacks when client is connected to the server. My question is do i have to unbind callbacks before deleting socket from the table of players ?

Here is my sample callback: 

 Player.prototype.viewPortListenerInit = function(){
  var self = this;

  this.socket.on('clientViewPortResize', function(data){
    self.clientViewPort = data;
  });

  };

Here is adding player to the list/hashset of players : 

this.list[socket.id] = new Player(socket);

And here is deleting:

socket.on('disconnect', function(){
       delete this.list[socket.id]
});

When there are no references to instance EventEmitter (like socket), it's garbage collected with its callbacks.
