javascript - Node.js update elements in MongoDB -

i have following mongoose schema , model:

var deviceschema = new schema({     deviceid:string,     devicename:string,     deviceplace:string,      socket : [{number: number,name:string, state : boolean, current: number, image:number,locked:boolean,reserved:boolean}] }); 

i have device in database 4 sockets.

here example!

this original data.

{     "_id" : objectid("5626569006bc3da468bafe93"),     "deviceid" : "0013a20040b5769a",     "devicename" : "device",     "deviceplace" : "place",     "__v" : 0,     "socket" : [          {             "_id" : objectid("5628bd83570be84e28879e2d"),             "number" : 0,             "name" : "name"             "state" : true,             "current" : 0             "image" : 0,             "locked" : false,             "reserved" : false,         }, ...     ] } 

and received data client update.

{     "_id" : objectid("5626569006bc3da468bafe93"),     "deviceid" : "0013a20040b5769a",     "__v" : 0,     "socket" : [          {             "_id" : objectid("5628bd83570be84e28879e2d"),             "number" : 0,             "name" : "new name!!!!!"             "state" : true,             "current" : 0         }, ...      ] } 

now i'm trying update specific socket's name in database following command:

device.update({deviceid: newdata.deviceid, "socket.number": newdata.number}, {$set: {"socket.$.name": newdata.name}}) 

newdata object extracted socket array in received data.

i want update first socket's name. or if possible, want update every socket's name received socket array.

but not seem working, no error. can pin point i'm doing wrong?
