"send" is no response in ionic

In my ionic project, it can't work normally.When I call this method, he didn't give me any return values.

setInterval(function () {
var buffer = new ArrayBuffer(12);
var x = new Int32Array(buffer);
x[1] = 1234;
var slice = buffer.slice(4);
var y = new Int32Array(slice);
console.log(x[1]);
console.log(y[0]);
x[1] = 6789;
alert($scope.socketId);
chrome.sockets.udp.send($scope.socketId, buffer,
'192.168.0.100', 8888, function(sendInfo) {
alert("sent " + sendInfo.bytesSent);
});
}, 5000);

This sockets has been created,and I can get the information by the method "chrome.sockets.udp.getInfo".
