does not re-render on state change

when the component receive new props or state it will not re-render,
example, passing props that change the url.
`componentWillReceiveProps(nextProps){
if(this.state.category !== nextProps.category){
this.setState({
category: nextProps.category
})
}
}`
but after changing the props or state if I pull the list it will render the new url (obviously).

also doing
`this.refs.listView._refresh()`
will not re-render the component

Start by reproducing the componentWillReceiveProps example with a changing category or URL, then inspect the listView entry point and its _refresh() behavior. Done means the list re-renders with the new props or state without requiring a manual pull or ref refresh.
