title: iterate through sub-objects of ng-repeat with dynamic key value pair
body: <p>I have a JSON object and I am iterating through this.</p>
  
  <p>But, each iterated object has some child objects where I do need to iterate through them as well.</p>
  
  <p>JSON structure:</p>
  
  <pre><code>[{
      'name': 'a',
      't1':'v1',
      't2':'v2',
      't3': {
          'c1':'cv1',
          'c2':'cv2',
           ...
      }
  }, {
      ...
  }]
  </code></pre>
  
  <p>This JSON object has (key, value) pair and value can have its children with (key, value) pair again.</p>
  
  <p>I wanted to create labels for each key value pair and for child key value pair also.</p>
