COM: BSTR in structure. How pass it?

Hi,
I have this problem:
I want to pass some structure with two BSTR strings from server to client.

SERVER SIDE:
============
part of my IDL:
---------------
typedef struct
{
      BSTR      text1;
      BSTR      text2;
} NWVaTestStruct;

....

interface INWVaTest : IUnknown
{
      [helpstring("method GetTestData")] HRESULT GetTestData([out] NWVaTestStruct** ppData);
      ....
};

....

part of H file of CNWVaTest class:
----------------------------------
STDMETHOD(GetTestData)(/*[out]*/ NWVaTestStruct** ppData);

part of CPP file of CNWVaTest class:
------------------------------------
STDMETHODIMP CNWVaTest::GetTestData(/*[out]*/ NWVaTestStruct** ppData)
{
      *ppData = new NWVaTestStruct;

      (*ppData)->text1 = (BSTR)CComBSTR("aaa");
      (*ppData)->text2 = (BSTR)CComBSTR("bbb");

      return S_OK;
}

CLIENT SIDE:
============
NWVaTestStruct* testData;

m_pVaTest->GetTestData(&testData);

CString sTemp1,sTemp2;
BSTR bstr;

sTemp1 = CString(testData->text1);
sTemp2 = CString(testData->text2);
----------------------------------------

Both strings, sTemp1 and sTemp2, contains "bbb". What's wrong?
How can I pass structure with BSTRs?

Thank you.
