Does not work in Haml

[skamansam]

I cannot get this to work in Haml files. I tried selecting text, not selecting any text, selecting multiple lines, selecting only the hash I want to convert, but nothing changes. Here are two lines I am trying to change:

    %input{:type=>:hidden,:name=>'subject_name',:value=>item.subject_name}
    %input{:type=>:hidden,:name=>'subject_datum[answers][last_item_path]',:value=>item.answer_path.to_json}
