Updating a React Input text field with the value on onBlur event

In order to have the input value editable you need to have an onChange handler for it that updates the value. and since you want to call a function onBlur, you have to bind that like onBlur={() => this.props.actions.updateInput()}

componentDidMount() {
   this.setState({inputValue: this.props.inputValue});
}
handleChange = (e) => {
  this.setState({inputValue: e.target.value});
}

<input value={this.state.inputValue} onChange={this.handlechange} onBlur={() => this.props.actions.updateInput(this.state.inputValue)} />
