title: Custom Value of Checkbox 'Y'/'N' instead of true/false. Angular 2
body: <p>I have a data which I want to display in a checkbox.The data has a boolean condition 'Y'/'N'. My problem is checkbox input only accepts true/false. Is there a way to change the value of checkbox that instead of true/false I want it to accepts 'Y'/'N';</p>
  
  <p>Sample Data:</p>
  
  <pre><code>[{
      "id": 1,
      "value": "0.59"
  }, {
      "id": 2,
      "value": "N"
  }, {
      "id": 3,
      "value": "LOW"
  }, {
      "id": 4,
      "value": "HIGH"
  }, {
      "id": 5,
      "value": "Y"
  }]
  </code></pre>
