How can I port a bound date input helper to HTMLBars?

Question

I'm trying to port a 'DateInputView' TextField extension with a bound helper to HTMLBars. It appears that 'call()' has been removed from 'Handlebars.helpers.view' so the helper doesn't work anymore. I've tried several syntax changes based on forums I've read but nothing works. The field is a datepicker which switches to the native calendar picker when using a mobile device. I see an example where the bound helper is integrated into the view helper code, so uses one js file rather than two, so am trying to go that route now. Code is below. If anyone who knows to to rework it for HTMLBars please let me know.

// ../templates/avail/navigation.hbs
{{date-input id="checkin" valueBinding="controllers.avail.arrival" class="form-control date-picker"}}

// ../views/date-input.js
var DateInputView = Ember.TextField.extend({
  didInsertElement: function(){
    Ember.run.scheduleOnce('afterRender', this, this._setupDateInput);
  },
  _setupDateInput: function(){
    var _this = this;
    var type = Ember.$(this.get('element')).attr('type');
    // Set up Date Picker for object
    if( type === "input" ) {
      Ember.$(this.get('element')).datepicker({
        format: "yyyy-mm-dd",
        autoclose: true
      });
    }
  }
});
export default DateInputView;

// ../helpers/date-input.js
import DateInputView from '../views/date-input';

export default Ember.Handlebars.makeBoundHelper(function(options) {
  Ember.assert('You can only pass attributes to the `input` helper, not arguments', arguments.length < 2);

  var hash = options.hash,
    types = options.hashTypes,
    inputType = hash.type,
    onEvent = hash.on;

  delete hash.type;
  delete hash.on;

  hash.type = "input";

  if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
    hash.type = "date";
  }

  hash.onEvent = onEvent || 'enter';

  return Ember.Handlebars.helpers.view.call(this, DateInputView, options);
});

I wound up re-working this viewHelper as a Component.
