Missing "keyboard autocomplete dictionary" on Android device with ng2-completer

I was able to successfully implement ng2-completer in my Ionic app, but the only thing I’m missing is the “keyboard autocomplete dictionary” when typing in a word in the input field.
Like for example here: https://i.imgur.com/qSyqzS2.png

For all input fields in Ionic you have to add ‘autocomplete=“true”’ and then it works, but not if I use ng2-completer as a field declared with ng2-completer doesn’t have that attribute.

Is this not possible in general with ng2-completer? I couldn’t find anything usefull in the documentation or by googling for it.
