Focus input when clicked

I am using ionic (v1) 2.2.1 and Cordova 6.5.0.
The ionic keyboard plugin is installed.
When I click on an input in the middle or bottom of the page, the keyboard shows up but the screen does not scroll to the clicked input field.
When I start typing, the screen scrolls to the chosen input.
But I would like to scroll right after the click in the input field.
How can I achieve that and which data may I have to check ?

This is my part in the app.js:

    .run(function($ionicPlatform) {
  $ionicPlatform.ready(function() {
    if (window.cordova && window.cordova.plugins && window.cordova.plugins.Keyboard) {
    if (window.StatusBar) {
      // org.apache.cordova.statusbar required

Thanks in advance and brgds
