Hello, some one can help me fix my problem? I want to re-render my layout, but extraData can't working fine...

Good catch, will fix.
fixed in 1.1.3
I think the problem is still there in verison 1.1.7. I can't update the list with extraData.
@computerjazz Looks like extraData is still not working v2.0.1
