setReturnKey of Native UI Text Field

I am trying to input a number text field and then submit the number with setReturnKey (I am assuming that this is what this function does?) When I build and test on my device, I am getting a keyboard showing but no return key, just the number pad and the backspace button in the bottom right.  Here is the code I have creating the text field:

        inputField = native.newTextField( W/2, 150, 300, 50  )         inputField.inputType = "number"         inputField.placeholder = "Enter Winnings"         inputField.align = "right"         inputField.size = 14         inputField:setReturnKey("done")         inputField:addEventListener( "userInput", textListener )

and I am calling this in the “did” phase in scene:show in composer.  Anyone have a similar issue?  It seems like a pretty simple function so there doesn’t seem like there are many places to go wrong.  

Also, I have found it difficult to find any useful documentation on this or the native UI in general so if you know of where I could find more help on this that would be great.

On iOS, the “number” keyboard does not have an Return Key.  12 buttons 0-9, a symbol and backspace button.
