title: how to know which radio button id selected of which row?
body: <p>I have make a demo in which I make rows with ids <code>tc_1</code>, <code>tc_2</code>, <code>tc_3</code> …… and so on.</p>
  
  <p>When I expand a row, I have two options and a button. I need to get know which row id and which option is selected?</p>
  
  <p>Example: I expand second row, It should alert <code>tc_1</code> with option select <strong>Add test case</strong>.</p>
  
  <pre><code>$('#list').on('click','.addClickClass',function(){
      alert('hii')
  });
  </code></pre>
