title: Bind text input value on change event - React Native + Redux
body: <p>I'm creating form in React Native and Redux. I added <code>TextInput</code> and want to change the state of this field in Reducer. I have a trouble, because I don't know how to add <code>(change) =&gt; this.setState({change})</code> function to my Redux architecture. I use combine reducers and have no idea how to bind that value. 
  Saying in short, I need to gain default behaviour of the <code>TextInput</code> on change function but I have to use Redux to do it. </p>
  
  <p>Form.js</p>
  
  <pre><code>const mapDispatchToProps = dispatch =&gt; {
    return {
        changeNameInput: () =&gt; dispatch({type: 'CHANGE_NAME_INPUT'})
    };
  };
  
  const mapStateToProps = state =&gt; {
    return {
        change: state.changeNameInput.change
    };
  };
  
  class Form extends React.Component {
    render() {
      return (
        &lt;View&gt;
           &lt;FormLabel&gt;Name&lt;/FormLabel&gt;
           &lt;TextInput
              onChangeText={this.props.changeNameInput}
              value={this.props.change}
          /&gt;
        &lt;/View&gt;
      );
    }
  }
  </code></pre>
  
  <p>Reducer.js</p>
  
  <pre><code>const initialState = {
      change: 'Your name'
     };
  
     const changeinputReducer = (state = initialState, action) =&gt; {
       switch (action.type) { 
         case 'CHANGE_NAME_INPUT':
  
    //Problem
  
           return {...state, change: '????' };
          default:
           return state;
       }
     };
  
     export default changeinputReducer;
  </code></pre>
