start a function when click on circle - leaflet

I make some circles in JS as follow:

L.circle(
  [46.765735535841024, 23.58344078063965], 5, {
    color: "blue"
  }).addTo(map).bindPopup("Description: This is my description");

I want to replace that bindPopup with a function. When I click the circle, instead of my description display, I want to run a function, for example I made this function:

function circleClick() {
     // my implementations;
}

Would someone tell me how could I do this possible?
