title: How to manually update datatables table with new JSON data
body: <p>I am using plugin <a href="http://datatables.net" rel="noreferrer">jQuery datatables</a> and load my data which I have loaded in DOM at the bottom of page and initiates plugin in this way:</p>
  
  <pre><code>var myData = [
      {
          "id": 1,
          "first_name": "John",
          "last_name": "Doe"
      }
  ];
  
  $('#table').dataTable({
      data: myData
          columns: [
          { data: 'id' },
          { data: 'first_name' },
          { data: 'last_name' }
      ]
  });
  </code></pre>
  
  <p>Now. after performing some action I want to get new data using ajax (but not ajax option build in datatables - don't get me wrong!) and update the table with these data. How can i do that using datatables API? The documentation is very confusing and I can not find a solution. Any help will be very much appreciated. Thanks.</p>
