Form inline not right aligned in nav example

Created by: Quy

Form inline should be right aligned but it is displayed left aligned.

<nav class="navbar navbar-light bg-faded justify-content-end">
  <form class="form-inline">
    <input class="form-control mr-sm-2" type="text" placeholder="Search">
    <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
  </form>
</nav>
