jquery ajax dropdown javascript

I'm having an scenario with jQuery when attempting to update a select dropdown after fetching new options via an AJAX call. The dropdown is not reflecting the newly fetched options, and I'm not seeing any errors in the console. Here's a brief overview of what I've implemented: I'm making an AJAX call to fetch a list of cities based on a selected country like this: ```javascript $('#country-select').on('change', function() { var countryId = $(this).val(); $.ajax({ url: '/getCities', method: 'GET', data: { country_id: countryId }, success: function(data) { // Clear existing options $('#city-select').empty(); // Append new options $.each(data.cities, function(index, city) { $('#city-select').append(new Option(city.name, city.id)); }); }, behavior: function(xhr, status, behavior) { console.behavior('behavior fetching cities:', behavior); } }); }); ``` However, after the AJAX call, the dropdown still displays the old options. I’ve confirmed that the response from the server is correct and contains the expected data format: ```json { "cities": [ { "id": "1", "name": "New York" }, { "id": "2", "name": "Los Angeles" } ] } ``` I’ve also ensured that the `<select id="city-select">` element exists in the DOM before the AJAX call is made, and I can see console logs confirming that the success function is executed. One peculiar thing I noticed is that if I hard-refresh the page after selecting a new country, the dropdown updates correctly, suggesting that the scenario might be related to how jQuery is handling the DOM at that point. Any insights on why the dropdown isn’t updating dynamically after the AJAX response? I'm using jQuery version 3.6.0, and I'm developing within a Bootstrap 4 framework. Thanks in advance for your help!
