IONIC APP- get device id for post service($http.post) - angularjs

Question

I'm trying to get the device id getUUID at the time of app login along with username and password. Is the right way to get device id and post it to the server for login.
controller.js
.controller('LoginCtrl', function($scope, $http,$rootScope,$window,$location,$cordovaDevice) {
$scope.login = function () {
var data ={
username : $scope.username,
password : $scope.password
};
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
$http.post('login', data, config)
.success(function (data, status, headers, config) {
// $scope.DataResponse = data;
$location.path('#/tab/new-order');
})
.error(function (data, status, header, config) {
$window.alert("username or password incorrect");
});
console.log(device.cordova);
}
var config = {
headers : {
'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8;'
}
}
};
})
html code
<form action="" class="ki-login-form" method="post" accept-charset="utf-8">
<div class="form-group username">
<input type="text" class="form-control" name="username" value="" id="identity" placeholder="Your Name">
</div>
<div class="form-group pin">
<input type="text" class="form-control" name="password" value="" id="identity" placeholder="Your Pin">
</div>
<a type="submit" class="btns" ng-click='login()' >Login</a>
</form>
After login it has to be directed to a page href="#/tab/new-order" in the ionic tab

Answer 1

Add dependency injection $location in controller function like following -
.controller('LoginCtrl', function($scope, $http, $rootScope,$window,$location) {
// Your code
});
Solution for your added comment -
Use following -
Add device plugin : cordova plugin add org.apache.cordova.device
In your controller :
module.controller('MyCtrl', function($scope, $cordovaDevice) {
var uuid = $cordovaDevice.getUUID();
});

Answer 2

Change this
var data = $.param({
username : $scope.username,
password : $scope.password,
});
to
var data = {
username : $scope.username,
password : $scope.password,
};
UPDATE -
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
console.log(device.cordova);
}
