How to run Mersenne Twister inside a function?

I have a short piece of code which runs the Mersenne Twister PRNG and it works great:

std::random_device randDev;
std::mt19937 twister(randDev());
std::uniform_int_distribution<int> dist(0,99);

for (int i = 0; i < 10; i++) {
    std::cout << dist(twister) << std::endl;
}

It outputs ten random numbers. However if I put the exact same code into a function:

#include <random>

int getRand(const int& A, const int& B) {
    std::random_device randDev;
    std::mt19937 twister(randDev());
    std::uniform_int_distribution<int> dist(A,B);

    return dist(twister);
}

int main() {
    for (int i = 0; i < 10; i++) {
        std::cout << getRand(0,99) << std::endl;
    }

    return 0;
}

It outputs the same number ten times. I'm just starting out with C++ so I have no idea what causes this or how to go about fixing the problem.
