Is there a way to pass arguments to getrandomnumber() function?

\startluacode
      local mathrandom = math.random
      local context    = context
      document.get_random_number = function (min,max,delta)
        context ("%0.1f", mathrandom (min, max) / decimal)
      end
    \stopluacode

    \def \getrandomnumber#1#2#3 {\ctxluacode {document.get_random_number
(#1,#2,#3)}}

    \starttext
      \bTABLE
        \bTR \bTD Distance (cm)          \eTD \bTD $\Delta t$ (s) \eTD \eTR
        \bTR \bTD[nr=3] \getrandomnumber{34,56,10} \eTD \bTD t1
\eTD \eTR
        \bTR                                  \bTD t2             \eTD \eTR
        \bTR                                  \bTD t3             \eTD \eTR
      \eTABLE
    \stoptext
