Форма, возвращающая нулевые значения

Question

Значения, которые я передаю во входные данные моей формы, возвращают null.

Modal-template:

<script type="text/ng-template" id="new-label.modal.html">
  <div class="modal-header">
    <button type="button" class="close" ng-click="vm.cancel()">
      <span aria-hidden="true">x</span>
    </button>
    <h4>Nova etiqueta</h4>

  <div class="modal-body">

          <input type="text" id="new_label" name="new_label" class="form-control" ng-model="vm.newLabel.name">

          </ui-select>
        </div>
        <div class="checkbox">
          <label>
            <input type="checkbox" ng-model="vm.newLabel.show_on_fid">

    <button class="btn btn-secondary" ng-disabled="vm.saving" type="button" ng-click="vm.cancel()"><%= t('label_modal.cancel') %></button>
  </div>
</script>

Modal- js:

function LabelsController($scope, $q, $timeout, $http, $uibModal) {
  var self = this;

  this.newLabel = {
    name: '',
    products: [],
    show_on_fid: []
  };
  this.productSearch = {};
  this.saving = false;
  this.loading = false;
  this.labels = {};
  this.page = 1;
  this.loadingPromise = null;
  this.allTagsSelected = false;

    this.createLabel = function () {
    $uibModal.open({
      templateUrl: 'new-label.modal.html',
      controllerAs: 'vm',
      controller: ['$uibModalInstance', function ($uibModalInstance) {
        var vm = this;

        vm.searchProducts = function (filter) {
          if (filter.length < 3) {
            var defer = $q.defer();
            defer.resolve();
            return defer.promise;
          }
          return $http({
            url: '/manager/products/get_products',
            method: 'GET',
            params: {
              filter: filter,
              page: 1
            }
          }).then(function (response) {
            vm.productSearch = response.data;
          });
        };

        this.save = function () {
          var newLabel = angular.extend({}, self.newLabel);
          newLabel.products = newLabel.products.map(function (product) {
            return product.id;
          });
          self.saving = true;

          $http({
            url: '/manager/labels.json',
            method: 'POST',
            data: {
              label: newLabel
            }
          }).then(function () {
            $.toast('Etiqueta criada com sucesso.', {type: 'success'});
            self.newLabel = {
              name: '',
              products: [],
              show_on_fid: [],
            };
            self.saving = false;
            $uibModalInstance.close();
          }, function () {
            $.toast('Houve um problema com a sua requisição. Tente novamente.', {type: 'error', duration: 10000});
            self.saving = false;
          });
        }

        this.cancel = function () {
          $uibModalInstance.dismiss('cancel');
        }
      }],
    }).result.then(function () {
      self.loadLabels();
    });
  };

Контроллер:

...

def create
    current_user_branch = current_user.get_branch_access
    @label = Label.create(vendor: @vendor, name: params[:label][:name], show_on_fid: params[:label][:show_on_fid], branch_id: current_user_branch)
    @label.products = Product.where(vendor: @vendor, id: params[:label][:products])
    render json: {status: :ok}
  end

Когда я ввожу имя для своей метки , выберите продукт, отметьте чекбокс и сохраните, на созданной этикетке не будет помечено название или продукт, будет отмечен только чекбокс. Что я делаю не так?
