Well,

I am answering my own question again, but maybe it is good feedback for
everyone. I used

for (int j=0; j<10; j++)
{
    char lBuffer[100];
    itoa(j, lBuffer, 10);
    strcat(lBuffer, "testClass");
    JS_DefineObject(sJSContext, sJSProto, lBuffer, &testClass, 0,
JSPROP_PERMANENT);
}

instead of the loop below and it works...
