If using forceUpdate() is discouraged, how should components react to change events in the model?

help you fix your problem Solved using MobX, a reactive paradigm that makes state observable and automatically upates observing components.

forceUpdate in nested components

I hope this helps you . Forceupdate is most likely not needed in this case. Any react component only should need a rerender when state changes or when props change.
And react handles this automatically.

Vue.js 2 - $forceUpdate() on components doesn't refresh computed properties?

I wish did fix the issue. Don't mutate a prop - they are not like data defined attributes. See this for more information:

this.forceUpdate() not re-rendering dynamically created components

will help you Only items inside this.state are properly monitored by React on whether or not a rerender should occur. Using this.forceUpdate does not check to see if this.questions has been changed.
Use this.questions as this.state.questions. When you do this, do not mutate this.state.questions. Instead, make a new copy of it and use this.setState on it.
constructor (props) {
  super(props);
  this.state = {
    questions: [<TextBox key={0}/>]
  }
  this.createTextBox = this.createTextBox.bind(this);
  this.loadTextBox = this.loadTextBox.bind(this);
}

createTextBox() {
  const newQuestions = [...this.state.questions, <TextBox key={this.questions.length}/>]
  // or you can use 
  // const newQuestions = this.state.questions.concat(<TextBox key={this.questions.length + 1}/>)
  this.setState({questions: newQuestions})
}

loadTextBox() {
  return (this.state.questions);
}

Vue Slot: How to parse then render slot components

seems to work fine You shouldn't be using template and computed properties if you want to programmatically render out inside . {{}} in templates are designed to perform basic operations of JS. The most appropriate way will be to use render function.
