React hooks update parent state from child

const EnhancedTable = ({ parentCallback }) => {
    const [count, setCount] = useState(0);
    
    return (
        <button onClick={() => {
            const newValue = count + 1;
            setCount(newValue);
            parentCallback(newValue);
        }}>
             Click me {count}
        </button>
    )
};

class PageComponent extends React.Component { 
    callback = (count) => {
        // do something with value in parent component, like save to state
    }

    render() {
        return (
            <div className="App">
                <EnhancedTable parentCallback={this.callback} />         
                <h2>count 0</h2>
                (count should be updated from child)
            </div>
        )
    }
}
