Script Editor webpart works correctly only in editor mode

I need customize NewForm for list for automatical filling some fields based on user's profile data. I add Script Editor webpart to NewForm.aspx page and write into this code:

<script type="text/javascript" src="/_layouts/15/jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="/_layouts/15/SP.UserProfiles.js"></script>

<script type="text/javascript">
  var clientContext;
  var personProperties;

  $(document).ready(
    function(){
      SP.SOD.executeFunc('sp.js', 'SP.ClientContext', sharePointReady);
    }
  );

  function sharePointReady(){
    clientContext = SP.ClientContext.get_current();
    SP.SOD.executeFunc('SP.UserProfiles.js', 'SP.UserProfiles.PeopleManager', getUserProperties);
  }


  function getUserProperties(){
    var targetUser = "<domain>\\<login>"; // I write real domain and login in this line

    var peopleManager = new SP.UserProfiles.PeopleManager(clientContext);

    var profilePropertyNames = ["PreferredName", "Department", "Title"];
    var userProfilePropertiesForUser = new SP.UserProfiles.UserProfilePropertiesForUser(
        clientContext,
        targetUser,
        profilePropertyNames);
    var userProfileProps = peopleManager.getUserProfilePropertiesFor(userProfilePropertiesForUser);
    clientContext.load(userProfilePropertiesForUser);
    clientContext.executeQueryAsync(
        function () { alert(userProfileProps[0] + " works in " + userProfileProps[1] + " as a " + userProfileProps[2]); },
        function () { alert("Failure") });
  }
</script>

In edit page mode code works fine. In published page I get exception with text "TypeError: this.get_context is not a function" on this line:

var userProfileProps = peopleManager.getUserProfilePropertiesFor(userProfilePropertiesForUser);

Why it happens and how I can fix it?
