  <p>Now I want to push new data(only the data part) to the existing model, inside /modelData/data.</p>
  
  <p>code I am trying -</p>
  
  <pre><code>sap.ui.getCore().getModel().getProperty("/modelData/data").push(response.data);
  </code></pre>
  
  <p>This code is pushing the data but as - </p>

  <p>After 19(old values) it is pushing all the objects inside 20th as 0, 1, 2... The Ideal way should be after 19 I should get 20, 21, 22 and so on. </p>
  
  <p>What changes I need to make to get this, Thank you ... please suggest.</p>
