Hi @Erman_Altindag,

If you mean the custom button in the lightbox, you should use the onLightboxButton handler and check the the button id, stmt like that:

scheduler.attachEvent("onLightboxButton", function(button_id, node, e){
    if(button_id == "notes"){
        alert("Notes!");
    }
});

If you want to know the id of the clicked event, please use onBeforeLightbox handler, save the id to the variable with global scope and then use it in the onLightboxButton.
