Does not work either.

I have now (I added a SimpleCheckBoxes that does reasonable what I
want, but where you always need three checkbox parameters):
    \def\SimpleCheckBoxes#1,#2,#3,#4\par{
      #1\par
      \hskip2.5em[\hskip1em] #2\par
      \hskip2.5em[\hskip1em] #3\par
      \hskip2.5em[\hskip1em] #4\par}

    \def\CheckBoxes[#1]%
     {\startitemize[packed]
      \processcommalist[#1]\doCheckBoxes
      \stopitemize}

    \def\doCheckBoxes#1%
     {\sym{\mathematics{\Box}}#1\par}

    \starttext

    Intelligent way\par
    \CheckBoxes Yes, No,   A little bit

    \blank
    Always three checkboxes and with the initial question\par
    \SimpleCheckBoxes Does this what you want?, Yes,   No, A little bit

    \stoptext

This gives:
    Intelligent way
    es, No, A little bit
    Always three checkboxes and with the initial question
    Does this what you want?
         [ ] Yes
         [ ] No
         [ ] A little bit

I attached the pdf also.
