It works for all but this didn't, I had all for this following code:

constructor(props) {
 super(props);
  this.state = {
   addchange: ''
  }
 this.handleInputAddChange = this.handleInputAddChange.bind(this);
}

handleInputAddChange = (e) => {
 e.preventDefault();
  this.setState({
   [e.target.name]: e.target.value
  })
}

<input type="text" name="addchange" onChange={this.handleInputAddChange} />

and pops ups the weird error, and for the last time I doubled check that most of my code like this works but this appeared React.js's error screen like this:

TypeError: Cannot read properties of undefined (reading 'handleInputAddChange')

Note that its the same format from my other code like this. and its weird why it didn't work in this one anymore.
