Function returns a Function

How am I returning another function? The compiler error I get (on Visual Studio) is "function returns function" 

template <>
class encoder<uint16_t, endian_swap> {
public:
    uint16_t opeartor () (uint16_t& value){
        // do something
    }
};

Because 

uint16_t opeartor ()

looks like a declaration of a function called opeartor which takes no arguments and returns uint16_t. Try

uint16_t operator ()
