title: Getting updated data from table
body: <p>I have recently started working with UI5. In my current task, I have displayed data in table using <code>JSONModel</code> and by using <code>TextField</code> in template I am allowing user to update the data.</p>
  
  <p>I have to get the updated complete table contents back in form of JSON so that I can update it back in database.</p>
  
  <p>I have tried <code>Table.getContextByIndex()</code> and <code>getProperty</code>, however I am not getting updated data. Please let me know how this can be done.</p>
