Flex Mobile - How to show Copy and Paste Menu items in Spark non-editable TextArea

I want to output the native Android menu like picture when I select my text
in TextArea which editable value is false and the selectable value is true.
It seems when editable textarea is true, but I want to show when it is false
too.
How can I do this?
