How to get question TITLE, not NAME?

Hi!

I need to force my surveys to have TITLE fields defined for all questions.
I know that if TITLE is not defined than NAME is used, but in my code i need to check (and retrieve it) if TITLE is defined despite the presence of NAME.
How can i achieve that?

JavaScript
this.creator.getAllQuestions().forEach(e=>{

  /*
  * I've tried:
  * - e.title
  * - e.getPropertyValue('title)
  * - e.getPropertyByName('title')
  * - e.hasTitle <-- checks NAME, not TITLE 
  * - e.fullTitle 
  * etc...
  * Apparently all of them check the NAME property
  */

 if(!e.title) //<-- check if TITLE field is filled
 {   
   e.title = customFunctionToFormat(e.name) // <-- set TITLE with a formated NAME 
 }


})

Thanks!
