How to use the ember-flexberry-designer/objects/uml-primitives/fd-uml-partition.create function in ember-flexberry-designer

this.createObjectData((function(x, y) {
        let jsonObject = getJsonForElement(
          'STORMCASE.UML.ucd.Boundary, UMLUCD',
          { x, y },
          { width: 20, height: 13 },
          { Name: '' }
        );
        let usecasePartitionObject = fdPartition.create({ primitive: jsonObject });
        this._addToPrimitives(usecasePartitionObject);
        return usecasePartitionObject.JointJS();
      }).bind(this), e);
    },
