react-redux connect不会重新渲染组件，但会更新道具

我有一个关于react-redux的问题，我正在玩一些小的测试代码，以了解它是如何工作的 .

Git repository with problematic code

一切看起来都正确，动作生成器，减速器，调度器，mapStateToProps和连接功能 .

我也会在这里粘贴代码：

没有国家变异 .

但是当子组件Todo（index.jsx）调用从main（有问题的组件）TodoBox（index.jsx）传递给它的函数（onClick事件）时，然后1.调度程序被触发2. reducer被触发并返回具有预期更新的新状态3 .mapStateToProps被触发并返回预期结果

但TodoBox组件不重新渲染从浏览器控制台我可以看到TodoBox的this.props已更新值 .

发生了什么，我无法理解，检查了很多文章和例子，但没有任何匹配 .

谁能发现问题，我需要帮助 .

app.js（反应入口点）

import React from 'react';
import ReactDOM from 'react-dom';
import TodoBox from './views/index.jsx';
import { createStore } from 'redux';
import { Provider } from 'react-redux';
import * as actions from './redux_actions.js';

var data = JSON.parse(document.getElementById('initial-data').getAttribute('data-json'));

const todosReducer = function (state={todos: data}, action) {
  switch(action.type) {
    case actions.UPDATE_TODO:
        let newState = Object.assign({}, state)
        let upd1 = updateRow(newState.todos, 'titel', action.todoUpdate.id, 'checked', action.todoUpdate.checked)
        newState.todos = updateRow(upd1, 'titel', action.todoUpdate.id, 'detail', action.todoUpdate.checked ? 'Done' : 'Sorry not done')
        return newState
      break;
    default:
        return state;
  }
}

function updateRow(tab, where, val, updfield, val2) {
    tab.forEach( (row) => {
        row[where] === val ? row[updfield] = val2 : null
    })
    return tab
}

var Store = createStore(todosReducer)

ReactDOM.render(<Provider store={Store}><TodoBox /></Provider>, document.getElementById("app"));
