Where is the keyboard form assistant?



I’m building a form using ioni, running the app on iOS (iPhone).
Let’s have this:

<form name="myForm">
 <input type="text" name="myfield" ng-model="mymodel" />

When the user finishes to type something in the input text, he expect to be able to hide the keyboard.
However, there is no “Done” button on the top of the keyboard.
It’s annoying since the keyboard takes a lot of place.

Is it a normal behavior? (I’m using ionic beta 12).
How could I fix this issue?

Note: The documentation well shows the assitant (“Done” button) on the input text image: http://ionicframework.com/html5-input-types/#overview
