React actually auto-binds methods to the current component:

In the TodoList component, rather than:

scope.props.onRemoveItem.bind(this, i)

Try:

scope.props.onRemoveItem.bind(null, i)

By providing null instead of this you'll allow React to do its own thing. Also you need to actually use the onClick handler:

{this.props.task}
