ReactJS: onClick change element

You can solve it a little bit more clear way:

class EditableLabel extends React.Component {

    constructor(props) {
        super(props);
        this.state = {
            text: props.value,
            editing: false
        };
        this.initEditor();
        this.edit = this.edit.bind(this);
        this.save = this.save.bind(this);
    }

    initEditor() {
        this.editor = <input type="text" defaultValue={this.state.text} onKeyPress={(event) => {
            const key = event.which || event.keyCode;
            if (key === 13) { //enter key
                this.save(event.target.value)
            }
        }} autoFocus={true}/>;
    }

    edit() {
        this.setState({
            text: this.state.text,
            editing: true
        })
    };

    save(value) {
        this.setState({
            text: value,
            editing: false
        })
    };

    componentDidUpdate() {
        this.initEditor();
    }

    render() {
        return this.state.editing ?
            this.editor
            : <p onClick={this.edit}>{this.state.text}</p>
    }
}

//and use it like <EditableLabel value={"any external value"}/>;

If I understand your questions correctly, you want to render a different element in case of an "onClick" event.

This is a great use case for react states.

Take the following example

React.createClass({ 
    getInitialState : function() {
       return { showMe : false };
    },
    onClick : function() {
       this.setState({ showMe : true} );
    },
    render : function() {
        if(this.state.showMe) { 
            return (<div> one div </div>);
        } else { 
            return (<a onClick={this.onClick}> press me </a>);
        } 
    }
})

This will change the components state, and makes React render the div instead of the a-tag. When a components state is altered(using the setState method), React calculates if it needs to rerender itself, and in that case, which parts of the component it needs to rerender.
