Is it possible to use RandomChoice to choose decrements or increments in variables?

I'm trying to do this:

i1 = 1;
i2 = 1;

RandomChoice[{
  (i1 = i1 + 1),
  (i1 = i1 - 1),
  (i2 = i1 + 1),
  (i2 = i2 - 1)}]

In order to chose randomly which variable is going to be incremented or decremented - but it's not working. I've also tried with -- and ++ but I had the same problem. I am clueless about what may be the problem.
