title: Issue with getting data from a JSON object
body: <p>I have a response from an Ajax POST request which looks like this:</p>
  
  <pre><code>{
      "columns": [
          "r"
      ],
      "data": [
          [
              {
                  "extensions": {},
                  "start": "http://localhost:7474/db/data/node/2762",
                  "property": "http://localhost:7474/db/data/relationship/2709/properties/{key}",
                  "self": "http://localhost:7474/db/data/relationship/2709",
                  "properties": "http://localhost:7474/db/data/relationship/2709/properties",
                  "type": "IS_CONNECTED_WITH",
                  "end": "http://localhost:7474/db/data/node/2763",
                  "metadata": {
                      "id": 2709,
                      "type": "IS_CONNECTED_WITH"
                  },
                  "data": {
                      "FOC_Type": "IRU",
                      "DuctType": "IRU",
                      "TrenchType": "IRU",
                      "linestringId": "53805"
                  }
              }
          ]
      ]
  }
  </code></pre>
  
  <p>The above is a string. What I am trying to access is the elements: <code>"FOC_Type":"IRU"</code>,<code>"DuctType":"IRU"</code>,<code>"TrenchType":"IRU"</code>,<code>"linestringId":"53805"</code>.</p>
  
  <p>I transform the string to JSON like this:</p>
  
  <pre><code>  var response = JSON.parse(response);
  </code></pre>
  
  <p>and then I try to access some of the values like this:</p>
  
  <pre><code>  var dataEquip = response[Object.keys(response)[Object.keys(response).length - 1]] // get the data from json obj
  
    var komvosName = dataEquip[0][2];
  </code></pre>
  
  <p>But I can not make it work.</p>
  
  <p>I found a work around in which I don't convert the response to JSON format and I play with the string. But that's not nice. 
  I would appreciate if someone could show me what I do wrong.</p>
