How to use the @jsonforms/core.Actions.update function in @jsonforms/core

onSelect(ev: MatAutocompleteSelectedEvent) {
    const path = composeWithUi(this.uischema as ControlElement, this.path);
    this.shouldFilter = false;
    this.ngRedux.dispatch(Actions.update(path, () => ev.option.value));
    this.triggerValidation();
  }

return () => {
      if  (isNotTuple(schema)) {
        dispatch(
          Actions.update(
            path,
            data => {
              const clone = data.slice();
              clone.push({});

              return clone;
            }
          )
        );
      }
    };
  }

set data(data: Object) {
    this._store.dispatch(Actions.update('', () => data));
  }

return () => {
      if (isNotTuple(schema)) {
        dispatch(
          Actions.update(path, data => {
            const clonedData = data.slice();
            clonedData.push({});

            return clonedData;
          })
        );
      }
    };
  }

    dispatch(Actions.update('', () => data));
  }
});
