reactjs - React semantic-ui Dropdown onChange not working

Here's the code:

class MenuContainerComponent extends Component {

    onInputWidgetMenuChange(event, data) {
        console.log(data);
    }

    render() {
        var inputWidgets = [];
        for (var i = 0; i < this.props.cdata.widgets.inputWidgets.length; i++) {
            var componentName = getComponentNameFromType(this.props.cdata.widgets.inputWidgets[i]);
            var key = "inputWidget" + i;
            inputWidgets.push(<Dropdown.Item key={key}>{componentName}</Dropdown.Item>);
        }

        return (
        <Dropdown style={childStyle} text='Input widgets' icon='keyboard' floating labeled button className='icon' onChange={this.onInputWidgetMenuChange}>
            <Dropdown.Menu>
                <Dropdown.Header icon='tags' content='Select a widget to add to canvas' />
                <Dropdown.Divider />
                {inputWidgets}
            </Dropdown.Menu>
        </Dropdown>
        )
}

I am trying to get an event on menu selection. 'onClick' is working in similar fashion but there is no event on menu selection.

AFAIK, since you're using Dropdown.Menu inside this Dropdown, the onChange won't work. It's for normal Drodowns (like selecting a value etc). Try creating a generic onClick and assign it to <Dropdown.Item />
