Toggle text + also call method with argument?

Question

Im trying to toggle change a text on spacebar press with jquery ( works ) but also try to call a method with custom argument. How would below code example needs to me modified to do this? I have tried all kinds of ways but don't understand how to add the argument in. Also please explain how this should work in jquery and what im missing ( as learning point )

My goal is to call the argument with "start" and "stop" on each keypress

document.addEventListener("keydown", function (e) {

        if (e.keyCode == "32"){

          e.preventDefault();
          $(".spacebar_left").text(function(i, v){
            return v === 'PUSH ME' ? 'DON"T PUSH ME' : 'PUSH ME'
            custommethod("start")
           })


        }
      });

Why not just:

document.addEventListener("keydown", function(e) {
    if (e.keyCode == "32") {
        e.preventDefault();
        $(".spacebar_left").text(function(i, v) {
            if (v === 'PUSH ME') {
                custommethod("start")
                return 'DON"T PUSH ME'
            } else {
                custommethod("end")
                return "PUSH ME"
            }
        })
    }
});

p.s.: in your example custommethod() is never called as it goes after return
