Angular clone object from function - json

Question

I try clone my response json, but the id is the same..
I want to clone an item in my json to facilitate the addition of content.
The problem is following the same ID, then the answer is to update and no new item ..
the function:
$scope.cloneItem = function(id) {
$scope.itemtoclone = allDB.get({section: section, id: id}, function(){
$scope.itemnew = new allDB({section: section});
$scope.itemnew = angular.copy($scope.itemtoclone);
$scope.itemnew.$save(function(){
$mdToast.show($mdToast.simple({position: 'top right'}).content('Clone criado!'));
});
});
}
and the response:
GET http://localhost:5000/posts/25 304 Not Modified 7ms
POST http://localhost:5000/25 201 Created 2ms
json object to clone:
{
"id": 25,
"title": "Willian busca protagonismo igual ao de Neymar: \"Sempre joguei assim\"",
"subtitle": "Com 94% de aproveitamento nos passes na estreia da Copa América, jogador tem chamado a
responsabilidade e dividido a missão de criar os lances com o camisa 10",
"slug": "brasil-post-1",
"published": true,
"originalDate": "2015-06-16T03:00:00.000Z",
"excerpt": "Com 94% de aproveitamento nos passes na estreia da Copa América",
"$promise": {},
"$resolved": true,
"cats": [
2,
3,
4,
5,
7
]
}
Resolved, It was not quite what I wanted, but I help!
$scope.cloneItem = function(id) {
$scope.getclone = allDB.get({section: section, id: id}, function(response){
console.log(response);
$scope.itemnew = new allDB({section: section});
$scope.itemnew.title = response.title;
$scope.itemnew.subtitle = response.subtitle;
$scope.itemnew.excerpt = response.excerpt;
$scope.itemnew.$save(function(){
$mdToast.show($mdToast.simple({position: 'top right'}).content('Clone criado!'));
});
});
}
