Ionic scrolling issue

I have done one simple application. I used ionic Nav bar (header). When deploy the app in windows device, the whole page getting scrolled.(Header also moving up from the page). How to prevent this??

Any one please suggest?

use following structure as per ionic documentation

Left Button


Right Button
Some content!

Coding should be

< ion-header-bar align-title=“left” class=“bar-positive”>
< div class=“buttons”>
< button class=“button” ng-click=“doSomething()”>Left Button
</ div>
< h1 class=“title”>Title!
< div class=“buttons”>
< button class=“button”>Right Button
</ div>
</ ion-header-bar>
< ion-content class=“has-header”>
Some content!
< /ion-content>
