Passing arguments by reference from javascript to activex object

I have created a COM object and call it as activex from a web page in javascript.
Is there a way to pass parameters by reference that will be occupied by the ActiveX object.
The only way I can get a value is:  as a - "[retval, out]"  --> means return value
My COM function signature: HRESULT GetProperties(                                    [in, out] BSTR pIn,                                    [out] ULONG* pOut1,                                    [out] ULONG* pOut2,                        
                                           [out,retval] BSTR* pOutRetVal);
pOut1 and pOut2 returns allways as 0 to the javascript.
My Javascript call:
var in, out1, out2, retVal;
var obj = new activexobject("AXname");
retVal = obj.GetProperties(in, out1, out2);
