Setting Highcharts piechart chartDefaults from calling jsx file in React

I am using the following syntax to render a Highcharts PieChart.

var ContainingClass = React.createClass({
  render: function() {
    return (
        <PieChart
            title={this.props.title}
            series={this.props.series}
        />
    );
  },
});

This works well, but I need to overwrite the tooltip field in PieChart. What can I change in ContainingClass to make this happen?

Edit: Here is a sample fiddle with PieChart - http://ift.tt/1jomOGV I know that I need to set the tooltip field and could do it in plain javascript or jquery. I don't know how to pass my desired tooltip value from ContainingClass in React.
