Can't use data binding on iOS picker like the Android picker!

	</Column>
</Picker>

Alloy.Collections.citiesAPI.fetch();

Hello, Please provide a full reproducible core that regenerates the issue. Perhaps with a sample project that we can use to test the issue. Thanks.

Attached a screenshot of the UI, collection binding works as expected. Please reopen with a reproducible app if you are still having the issue.

   <Alloy>
   	<Collection src="color"/>
   	<Window>
   		<Picker id="color_picker" >
   			<Column dataCollection="color">
   				<Row title="{name}" />
   			</Column>
   		</Picker>
   	</Window>
   </Alloy>

The picker data doesn't change when data is fetched after the picker rendered. you should get the data first then you've to create a picker and put the data in. So the trick is call `$.color_picker.reloadColumn($.color_picker.columns[0]); after fetching success You've to test that with a real HTTP request, not with local data.
