title: Converting Angular 1 to Angular 2 ngInit function
body: <p>In angular1, we call the function ng-init based on ng-if condition. The following code represents If first div match with date &amp;&amp; time then it will check the second condition, checked or not checked. If checked then it's automatically call play() function and if it's not check then call the pause function. </p>
  
  <pre><code>&lt;div ng-if="ramadan.date === date &amp;&amp; ramadan.time === clock"&gt;
    &lt;div ng-if="ramadan.checked" ng-init="play()"&gt;&lt;/div&gt;
    &lt;div ng-if="!ramadan.checked" ng-init="pause()"&gt;&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I want to convert this code by angular2 typescript. Is there any way to automatically call the function based on condition in angular 2?</p>
