DatePicker在react.js中不起作用

Question

我在React.js中为Datepicker编写了一个代码，但它无法正常工作：

var DatePicker = React.createClass({

getInitialState: function () {
    return {
        currentDate: Moment().format('MM/DD/YYYY')
    };
},
prev: function () {
    var dateForHandler = new Date(this.state.currentDate);
    var dateForState = new Date(this.state.currentDate);
    this.props.dateHandler(dateForHandler.setDate(dateForHandler.getDate() - 7));
    this.setState({currentDate: Moment(dateForState.setDate(dateForState.getDate() - 7)).format('MM/DD/YYYY')});

},
next: function () {
    var dateForHandler = new Date(this.state.currentDate);
    var dateForState = new Date(this.state.currentDate);
    this.props.dateHandler(dateForHandler.setDate(dateForHandler.getDate() + 7));
    this.setState({currentDate: Moment(dateForState.setDate(dateForState.getDate() + 7)).format('MM/DD/YYYY')});

},
render: function () {
    var currentDate = this.state.currentDate;
    return (
        <div className="col-md-12 text-center mar_top_bottom">
            <Button text="" key="prev" click={this.prev} css="arrow_icon_backg arrow_left_icon pull-left"/>
            <p className="text_padding">{Moment().format('MM/DD/YYYY')==currentDate?'This Week':'Week of '+currentDate}</p>
            <Button text="" key="next" click={this.next} css="arrow_icon_backg arrow_right_icon pull-right"/>
        </div>
    );
},
componentDidMount: function () {

},
componentWillUnmount: function () {

}

我创建了一个contrl DatePicker.js。上面的代码写在DatePicker.js上。

我在js页面上调用此datepicker，然后datepicker将不会来。
