ES6 template is not working

[unbug]

How to make ES6 template working?

<DefaultLayout title={this.props.title}>
        <script dangerouslySetInnerHTML={{__html:`
          function test(a){
            alert(a);
          }
          test();
        `}} />
</DefaultLayout>

I got error React.createElement("script", {dangerouslySetInnerHTML: {__html: ^ Unexpected token ILLEGAL`

Are you specifying harmony: true when creating the engine?
