Ionic ionScroll now working with AmCharts

I'm trying to make basic chart (created using AmChart library) scrollable n axis X with using ionScroll component:

http://ionicframework.com/docs/api/directive/ionScroll/

Problem is that, if im using to move in ionScroll component on mobile device i get error message:

E/Web Console﹕ Uncaught TypeError: Cannot call method 'contains' of undefined:2882

I don't know if this problem is caused by amchart or ionic but it does not working on mobile devices (in Chrome with emulation of the mobile device it is working).

I'm using Ionic version: v1.0.0-beta.13 "lanthanum-leopard

Could somebody idea, what can causing this error?

Many thanks for any help.

Here is attached content of the template where is chart div and ion-scroll:

<ion-view title="Hourly charts" animation="slide-in-up">

    <ion-nav-buttons side="left">
        <button class="button button-icon icon  ion-arrow-left-c" ui-sref="home">
        </button>
    </ion-nav-buttons>

  <!--content-->
  <ion-content ng-controller="HourlyChartsCtrl"
               ng-init="setDateRange('today');">
      <div class="chart_range_date">
        Date: {{dateFrom}} 8 AM - 6 PM
      </div>
      <!--daily charts-->
      <ion-scroll
          id="scroll_hourly"
          style="width:100%;"
          class="vh72"
          direction="x"
          has-bouncing="false"
          locking="false"
