Generating Random Numbers between a range

So, i'm attempting to generate a random number between 1 and 61 using an overloaded parenthetical operator, however for some reason every time I run my code, I keep getting the same result of 49.

Here's what I have:

double operator()() const
    {
        std::uniform_int_distribution<int> _uniformIntDistribution(1, 61);
        std::default_random_engine _generator;

        double result;

        result = _uniformIntDistribution(_generator);



        return result;
    }

Not sure what i'm doing wrong. Any suggestions?

Thanks in advance!
