Won't rerender row when set datasource at setState

[xp19870106]

After I get new data from network and set the new datasource, the row just rendered the old data not the new ones!

@xp19870106
var ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !== r2});
rowHasChanged makes a decision whether to re-render row or not. maybe this will help you.

I'm also having problems with re-rendering. after I do
this.setState({ dataSource: ds.cloneWithRows(this.wall_posts) });
on successfully fetching data from server, nothing re-renders until i scroll a screen for a little. someone met this bug or I'm doing something wrong?
