React onClick event on component

I have a React component called <SensorList /> that has many child <SensorItem />s (another React component). I want to be able to declare an onClick event on each <SensorItem /> from within <SensorList />. I have tried doing the following:

sensorSelected: function(sensor) {    console.log('Clicked!');},render: function() {    var nodes = this.state.sensors.map(function(sensor) {        return (<SensorItem onClick={ this.sensorSelected } />        );    }.bind(this));    return (<div className="sensor-list">            { nodes }</div>    );}

Needless to say, I do not get any "Clicked!" coming up in my console. The React inspector in Chrome indicates that an onClick event is registered, with the above function body as it should be.

I conclude, therefore, that I can't register onClick events on the actual <SensorItem /> tags (I'm not sure why this is, however). How do I go about achieving this otherwise?
