fileIncorrectMessage of VaFileUpload not working

[chessparov]

• I'm submitting a ...

  • bug report

• What is the current behavior?
  Trying to modify the default message displayed when trying to upload wrong file types in a VaFileUpoad using the fileIncorrectMessage property, but it seems to do nothing

• If the current behavior is a bug, please provide the steps to reproduce, ideally also a screenshot or gif if it's a style issue

  

• What is the expected behavior?
  The message displayed in the modal should adapt to the string I passed to fileIncorrectMessage property. I tried with different strings and even passing the value with javascript, but with no luck so far
