React Native: Force Reload TabBarIOS.item

I have a TabBar based application in React Native. Multiple tabs use the same data source (AsyncStorage). If I update the data in one tab and open another, the old data is displayed. I cannot figure out how to force a reboot every time an item becomes active.

FavoritesView: display saved data
ExploreView: Manipulating Stored Data

FavoritesView: expired data is displayed (-> force reboot)

<TabBarIOS.Item
title="Explore"
icon={{uri:'ic_explore'}}
  selected={this.state.selectedTab === 'exploreTab'}
  onPress={() => {
    this.setState({
      selectedTab: 'exploreTab'
    });
  }}>
  <ExploreView/>
</TabBarIOS.Item>

<TabBarIOS.Item
  title="Favorites"
  icon={{uri:'ic_favorite_border'}}
  selected={this.state.selectedTab === 'favoriteTab'}
  onPress={() => {
    this.setState({
      selectedTab: 'favoriteTab'
    });
  }}>
   // Reload this
  <FavoritesView/>
</TabBarIOS.Item>

<TabBarIOS.Item
  systemIcon="more"
  selected={this.state.selectedTab === 'moreTab'}
  onPress={() => {
    this.setState({
      selectedTab: 'moreTab'
    });
  }}>
  <MoreView/>
</TabBarIOS.Item>

I already tried to set a new state to start the update, but it does not change anything.

<TabBarIOS.Item
      title="Favorites"
      icon={{uri:'ic_favorite_border'}}
      selected={this.state.selectedTab === 'favoriteTab'}
      onPress={() => {
        this.setState({
          selectedTab: 'favoriteTab',
          forceUpdate: Math.random()
        });
      }}>
      <FavoritesView forceUpdate={this.state.forceUpdate}/>
</TabBarIOS.Item>
