How to change a file name of a google form bu Apps script

Question

For a google spreadsheet it is easy to change the filename by using this script:

var file = SpreadsheetApp.openById(Idfile);
file.rename("new name");

Logical to me for change file name of a form:

var form = FormApp.openById(Idform);
form.rename("new name");

However this does not work!

Who knows the solution to change a filename of a google form by using apps script?
