title: React Checkbox not getting value onCheck
body: <p>React Checkbox not getting value onCheck . I tried an accepted answer, and get constant value first , but it is getting undefined(data variable)</p>
  
  <pre><code>&lt;TableCell&gt;
      &lt;Checkbox name="myCheckBox1" onChange={(e, data) =&gt; this.checkchange1('2', data.value)}/&gt;
  &lt;/TableCell&gt;
  
  
  checkchange1 = (e, data) =&gt; {
          console.log('it works');
          console.log(data.value);
      }
  </code></pre>
  
  <p>what am I missing ?</p>
