php - Is using Jquery's .on() function good practice? Or is there a better way

Question

Using .ajax() I am dynamically loading a list of images where the path is based on a "select" .trigger().

My "delete" function worked before loading the images on document ready but not after. I was able to get it working again by using .on() but am wondering if there is a better way.

Is is good practice to use this function or should it be a last resort?

$(document).ready(function(){

$("#displayGallery").change(function () {

//ajax

}).trigger('change');
});


$(document).on("click", ".deletepic", function(){

//ajax

return false;
});
