title: Ionic 2: ion-content doesnt scroll up on keyboard
body: <p>I am creating an Ionic 2 mobile app and am having some problems with input fields and keyboards. For now, I am only referring to iOS. This is the page without any input activated.</p>

  <p>Now, If I tap on CVV or Postal Code input fields, the keyboard does not push the ion-content up so the cvv or postal code fields are in focus above the keyboard.</p>

  <p>If I tap on postal code field, the entire input is covered by the keyboard. No scrolling happens. Before this issue, when the keyboard would open the content would squeeze up above the keyboard, but the content would squeeze, not push up off the screen if it is too large to fit the content.</p>
  
  <p>Anyone have advice on how to do this? I do not think it requires any plugins to control the content or keyboards. It seems to have something to do with styling with percentages.</p>
