it helps some times Why not to use just setState? It will re-render your component automatically.
code :
.then((res) => this.setState({ deletedId: logId }))
{this.state.deletedId && <span>deleted id: {this.state.deletedId}</span>}

Update component within handleClick React

it fixes the issue Instead of returning a new JSX element, you could use the state to save id and text, then update the state on click.
code :
class NavbarList extends React.Component {
 constructor() {
    this.state = {
      text: "Old Text",
      id: 0
    this.onClick = this.handleClick.bind(this);

  handleClick(event) {
    const {id} = event.target;

       text: "New text",
       id: 1

  render() {
     return (	
         <h3 id={this.state.id} onClick={this.onClick}>{this.state.text}</h3>

  <NavbarList  />,
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>
<div id="root"></div>

handleClick function not working on parent component?

help you fix your problem In your QuestionCard component, you never call the click handler you passed as props.
You need to call the this.props.handleClick to trigger the parent's onClick handler.
code :
 handleClick(choice) {
     this.setState(prevState => ({hideDiv: !prevState.hideDiv});

it should still fix some issue I am setting out to learn some react, and I am trying to create a grid of clickable buttons. For now all I want is to change the color of the button once it is clicked. , The problem is in the way of your state initialization:

In React, how do I pass arguments into a parent component's handleClick function?

By : Alberto Quinteri

should help you out Try to do this without using arrow function definition inside props (bad for child components performance, as will always be a new function reference more info here)
Parent class does not need the arrow function defined when passing onClick to BettingChips, we can do this at the class level instead, using arrow function to lexically bind this...
code :
class SomeParentComponent extends Component {

  handleClick = (betAmount) => {

  render() {
    return <BettingChips onClick={this.handleClick} />

class BettingChips extends Component {

  onClick = (e) => {

  render() { 
       <button onClick={this.onClick} value={1}>1</button>
       // ... etc
