Answer 1

AFAIK you can't assemble your data binding that way. Data binding is an EL expression, not SSJS. You could try to trick using ${} to compute #{}

Answer 2

As per Stefan, using SSJS (javascript:) to define a value for an input control results in it only being read-only. For values to be editable they must be bound using Expression Language (EL). For something as complex as the example (looping over a list of field/variable) you will most likely have to learn a little Java to allow you to connect your input controls to the bean via EL. If the purpose of the code is to have one field editable and the other read-only you should (as Per suggested) change the control from being an inputText to just (computed) text or a label and remove the event handler. Somebody reading the code could easily be confused in thinking you intended both to be editable.
