我想在 onChange 事件上更新问题名称。但问题是，如果我只更改一个问题，则每个问题都会更改。如何解决？

class QuestionCreate extends React.Component {
    constructor(props){
        super(props);
        this.state = {
            datas: [],
            default_question: {
                isNew: true,
                question: {
                    name: 'Click to write the question text',
                    answer_options: [
                        {name: 'click to write choice 1', 'choice': true},
                        {name: 'click to write choice 1', 'choice': true},
                        {name: 'click to write choice 1', 'choice': true},
                    ]
                }
            }
        }

    }


    onChangeQuestion(qustions, index, event){
        let all_data = this.state.datas;
        let currentQuestion = all_data[index].question
        all_data[index]['question']['name'] = event.target.value;
        console.log(all_data[index]['question']['name'])
        this.setState({datas: all_data})

    }

    displayRow(){
    let rowData = this.state.datas.map( (data, index) =>{
        console.log("this is data:", data, index);
        return(
            <div className="well" key={ index }>
                <h3>Q. <input type="text" onChange={ this.onChangeQuestion.bind(this, data, index) } value={ data.question.name } /></h3>
                    <ul>
                        <li>option</li>
                    </ul>
            </div>
        )
    })

    return rowData;
}
