VisibilitySensor onChange triggers on render

My component looks something like this
```
class MyComponent extends Component {
onChange(isVisible){
this.setState({visCount : this.state.visCount + 1}) //
}
render(){
return

}
}
```
The issue is `onChange` is getting triggered on every render, which then triggers another render so visCount keep auto-incrementing. Am I doing something wrong here? How are you supposed to use setState in onChange?
