title: Angularjs divide ng-model value and show it in textbox
body: <p>Hi I have a textbox that get a number value which it displays well but I want to convert that value by dividing it by 60.   </p>
  
  <pre><code> &lt;input ng-model="customer.balance" name="" type="text" class="form-control" id="limit" placeholder="Enter limit"&gt;
  </code></pre>
  
  <p>So the customer.balance value from the database is 600 seconds but I want it to show 10 which is in minutes. When I tried the following </p>
  
  <pre><code> &lt;input ng-model="customer.balance/60" name="" type="text" class="form-control" id="limit" placeholder="Enter limit"&gt;
  </code></pre>
  
  <p>I get the non-assign error. How do I do this conversion on the html input ng-model   </p>
