react组件中新添加了部分DOM为什么显示不出来

Question

import React from 'react';
import AddCharacterStore from '../stores/AddCharacterStore';
import AddCharacterActions from '../actions/AddCharacterActions';

class AddCharacter extends React.Component {
constructor(props) {

super(props);
this.state = AddCharacterStore.getState();
this.onChange = this.onChange.bind(this);

}

componentDidMount() {

AddCharacterStore.listen(this.onChange);

}

componentWillUnmount() {

AddCharacterStore.unlisten(this.onChange);

}

onChange(state) {

this.setState(state);

}

handleSubmit(event) {

event.preventDefault();

var name = this.state.name.trim();
var gender = this.state.gender;
var wins = this.state.wins;

if (!name) {
  AddCharacterActions.invalidName();
  this.refs.nameTextField.focus();
}

if (!wins) {
  AddCharacterActions.invalidWins();
}

if (!gender) {
  AddCharacterActions.invalidGender();
}

if (name && gender && wins) {
  AddCharacterActions.addCharacter(name, gender, wins);
}
