I try but dont send new data, see my example:

     app.controller('FormCtrl', function ($scope, $http, $httpParamSerializerJQLike, $state) {

  $scope.submitForm = function() {

$http(
  {
    method: 'POST',
    url: url+ 'save_edit_document',
    data: $httpParamSerializerJQLike($scope.doc),
    headers: {'Content-Type': 'application/x-www-form-urlencoded'}
  }
  ).success(function(){
  $state.go('showDoc', {'itemId': $scope.doc.id});
      });
    };
  });
