How do I get selected Items from ListItemPicker react control?

[PraveenM]

<ListItemPicker listId={this.state.selectedList}
                  columnInternalName="Title"
                  itemLimit={5}
                  context={this.props.context}
                  onSelectedItem={this.onSelectedItem} />

private onSelectedItem(carNumbers: { key: string; name: string }[]) {

  this.state.ListItemPickerItems.length = 0;

  for (const carNumber of carNumbers) {

    this.state.ListItemPickerItems.push(carNumber.name);

    alert(`Item value: ${carNumber.name}`);

  }

}
