Thank you Matt, you are right !!
with js_enumerate in c++, we can retrieve all parameter names of the 
function (parameters appear at the top of the enumeration).
Now, i just need to give parameter values to my js_callFunctionValue(). I 
think js_convert() should be
the right solution ?!

Thank you again.
