Have you any solution ?

    @GautamSheth This is not recommended due to performance reasons and tslint in SPFX solution won't even allow it. – Lukas Nespor Jan 10 at 10:51

You have to use arrow function in this.state.items.map this in anonymous function has different context and you would have to bind also the anonymous function itself like:

this.state.items.map(function (item, key) {
    return (
            <button onClick={this.showDialog}>click</button>
        </div >

Correct use:

this.state.items.map((item, key) => 
        <button onClick={this.showDialog}>click</button>
