Input Value doesn't change when selecting an option in react-select

I'm using react-select to define a select input control in my react application. This is how I'm using the component:

<Select
   onChange={function(e) {console.log(e)}}
   options={[
      {value: "sf", label: "San Francisco"},
      {value: "nyc", label: "New York City"}
   ]}
></Select>

Before selecting any option I see a Select... placeholder as the input value. This doesn't change after selecting an option: the input value doesn't change and the Select... placeholder appears to be the selected "option".

Is there something wrong with how I'm using the component?

Define the Select value in state variable, and logChange function will return an object, assign the value of that object to state variable, it will work, Check this code:

class App extends React.Component{

  constructor(){
     super();
     this.state = {value: ''}
  }
   
  logChange(val) {
    console.log("Selected: " + val.value);
    this.setState({value: val.value});
  }

  render(){
    var options = [
       {value: 'one', label: 'One' },
       {value: 'two', label: 'Two' } 
    ];
    return(
      
      <Select
          name="form-field-name"
          value={this.state.value}
          options={options}
          onChange={this.logChange.bind(this)}
      />
      
    )
  }
}

ReactDOM.render(<App/>, document.getElementById('app'))
