I'm working on a map-based app that uses Google Map API to create markers and its info window in React.js. The `infowindow.setContent()` only accepts either a `String` or `HTML`. It's impossible for me to pass in `String` as I have a `button` that links to a specific method in another react component (something like: `_this.props.addList(place)` ). Thus I must fill the argument as HTML DOM as the following lines of code:

```js
var div = document.createElement('div');
var title = document.createElement('h4');
title.innerHTML = place.name;

var btn = document.createElement('button');
btn.className = 'btn btn-danger btn-block';
btn.appendChild(document.createTextNode('I want to go here !!'));

div.appendChild(title).appendChild(btn);

google.maps.event.addListener(marker, 'click', function() {

  infowindow.setContent( div );
  infowindow.open(map, this);
});

btn.addEventListener('click', function() {
  _this.props.addList(place);
});
```

The codes work for me but I don't wanna create elements one by one. I've also tried to pass the argument with a React component but it seems not working:

```js
createMarker: function() {

  /** Some other lines of code */

  var _this = this;

  google.maps.event.addListener(marker, 'click', function() {

    infowindow.setContent( _this._renderInfoWindow(place) );
    infowindow.open(map, _this);

  });

},

// my infowindow rendering method
_renderInfoWindow: function(place) {
  return(
    <div>
      <h4>{place.name}</h4>
      <p>{place.cost}</p>
      <button className="btn btn-danger btn-block" onClick={this.props.addList.bind(this, place)}>I want to go here !! </button>
    </div>
  )
},
```

so is there another way to at least convert a react component to HTML so that I don't have to write `document.createElement()` one by one?

Thanks
