怎么去掉ionic的scroll属性

Question

怎么让背景图和内容同时滑动？
<ion-view id="view-account-signUp" view-title="{{setTitle('注册')}}" ng-controller="TibetRegisterCtrl" ng-form="userForm">

<ion-header-bar >
    <a class="button button-clear icon-left ion-ios-arrow-left"
       ng-click="back()"></a>
    <div class="title">注册</div>
    <!--<a class="button button-clear"  ng-disabled="userForm.$invalid" ng-click="submit()">下一步</a>-->
</ion-header-bar>
<ion-content class="padding-top " scrolling="no" style="background-color: transparent;background-image: url(/res/img/view/tibet/bg-1.png?v=1);background-repeat: no-repeat;background-size: 100%" >
