Cannot change keyboard type for an inline string editor

[cdarken]

I've tried this:

CBCellStringInlineEditor *usernameEditor = [CBCellStringInlineEditor cellWithTitle:NSLocalizedString(@"Display name", nil) 
valuePath:@"username"];
usernameEditor.keyboardType = UIKeyboardTypeAlphabet;

and this:

CBCellStringInlineEditor *emailEditor = [CBCellStringInlineEditor cellWithTitle:NSLocalizedString(@"Email", nil) 
valuePath:@"email" 
editor:[CBEditorStringInline editorWithKeyboardType:UIKeyboardTypeEmailAddress]];

but I always get the default keyboard.
