Fire radio button change action after dynamically created on ajax

Hi stackoverflow community

I'm trying to work with the on change event of radio buttons that are created dynamically from an ajax call. These radios are created based on a MySQL result and each radio button should listen to an onChange event.

Here is my ajax call:

$.ajax({
        ...
        success:function(ajax_result){
            ajax_result.forEach(fn_Populate); // could be replaced with for loop
            function fn_Populate(element){
                $("xdiv").append("<input type='radio' id='radio_"+element[0]+"' name='xradio'>");
                $("xdiv").append("<label for='radio_"+element[0]+"'>"+element[0]+"</label>");
            }
        }
});

This should create the radio buttons according to the ajax result, example radio_1, radio_2, radio_3, all with name xradio.

After the radio buttons are created, I need to identify when a button is clicked. Here is the code in jquery:

$("input[type=radio][name=xradio]").change(function(){
    alert("DO SOMETHING");
    // rest of code 
});

The problem is that the change event is not fired if it is outside of the ajax call.

I need to fire it outside of the ajax call because it will generate another dynamic button through a new ajax call.

All help will be appreciated.

Thanks

Consider the following.

$("#xdiv").on("change", "input[name=xradio]", function(event){
  console.log("Change on " + $(this).attr("id"));
});

This is using delegation to bind the event callback to a static element that is the parent of the dynamic element. The delegation allows it to be triggered by the child element.
