Socket.io error sending message to socket

There is a code line:

io.sockets.socket(socketid).emit('counter', { all : data.all, dialog : data.dialog });

It gives me exception:

TypeError: Object #<Namespace> has no method 'socket'

My connection event:

io.sockets.on('connection', function(socket) {});

Why object socket is no?

Full code:

var socketio = require('socket.io');
var server = http.createServer(app).listen(8181, function(){
    console.log("Express server listening on port "+ app.get('port') +" in "+ app.get('env') +" mode.");
});

var io = socketio.listen(server);
io.on('connection', function(socket) {});

Socket server creation for use with express. Look at http://socket.io/docs/ for more information and help.

var app = require('express').createServer();
var io = require('socket.io')(app);

app.listen(8181);

io.on('connect', function(socket) {
    socket.on('example', function(data) {
        //parse the data, do something, create response data object, etc.

    });
});

And with HTTP + Express

var app = require('express')();
var server = require('http').Server(app);
var io = require('socket.io')(server);

server.listen(8181);

io.on('connect', function(socket) {
        socket.on('example', function(data) {
            //parse the data, do something, create response data object, etc.

        });
    });

For the emit you are trying to create (my below example will broadcast only to the connected socket, by providing the .to(socket.id) )

io.to(socket.id).emit('counter', {all : data.all, dialog : data.dialog});
