I'm pretty sure if you give your mobileControl a name (FMyText) in this 
case, then that is the only way you can refer to it. You can only use 
'the result' of the Create function *if* you didn't give it a name.

So you need to do either:

   mobileControlCreate "input", "FMyText"
   mobileControlSet "FMyText", ...


   mobileControlCreate "input"
   put the result into sinputID
   mobileControlSet sinputID, ...
