  <p>I need to format the date like "yyyy/MM/dd" because that's how my RESTapi receives the args.
  Applying $filter in angular.</p>

  <p>It seems that the problem was solved, however when I change the date in the datepicker, the format date changes to a format like <code>2014-01-30T00:58:43.000Z</code></p>
  
  <p>how can I set default format date with this tool? </p>
