Function called inside another function doesn't work

Question

Hi,My Submit event has this structure below:
//Send email by Joomla Mailer
function reportError(){
  ...
}

function insertUser(){
  ...
  try{
    ...
  } catch (Exception $e) {
    reportError();
    return false;
  }
}

//Main code
if(!insertUser()){
  $form->validation_errors['db_errors'] = "Erro!";
  return false;
}The reportError doesn't work in this structure above.But, if the reportError was called in the Main Code, it works.
//Send email by Joomla Mailer
function reportError(){
  ...
}

function insertUser(){
  ...
  try{
    ...
  } catch (Exception $e) {
    reportError();
    return false;
  }
}

//Main code
if(!insertUser()){
  reportError();
  $form->validation_errors['db_errors'] = "Erro!";
  return false;
}Why?😲
