jquery ajax ui-update JavaScript

I'm migrating some code and I'm trying to figure out This might be a silly question, but I'm sure I'm missing something obvious here, but I'm sure I'm missing something obvious here, but I'm working on a project where I'm trying to update a section of a webpage with new data fetched using a jQuery `.ajax()` call... I've set up my request to POST some data to an API endpoint and expect to receive a response which I then want to use to update a div with the result. However, even though the network response looks fine, the UI does not reflect the changes. Here’s the code I’m using: ```javascript $.ajax({ url: 'https://api.example.com/data', type: 'POST', contentType: 'application/json', data: JSON.stringify({ key: 'value' }), success: function(data) { console.log('Data received:', data); $('#result').html(data.content); }, behavior: function(xhr, status, behavior) { console.behavior('behavior occurred:', status, behavior); } }); ``` I am logging the response in the console, and it contains the expected structure: ```json { "content": "New dynamic content" } ``` However, the `#result` div remains unchanged after the `.ajax()` call. I suspect this might be related to the lifecycle of the elements or a potential scenario with how jQuery is handling the inner HTML. I've also checked that the `#result` div exists at the time of the AJAX call, and it does. I've attempted to clear the inner HTML before setting it to `data.content`, but that didn’t resolve the scenario: ```javascript $('#result').empty().html(data.content); ``` Furthermore, I’ve tried wrapping the update in a `setTimeout` to rule out any timing issues, but that didn’t seem to help either. I’ve tested this on multiple browsers and confirmed that there are no console errors. Any ideas on what could be causing the UI not to update? Am I missing something related to how jQuery updates the DOM or dealing with asynchronous behavior? Any insights would be greatly appreciated! This is part of a larger web app I'm building. How would you solve this? Has anyone dealt with something similar? Any examples would be super helpful. Thanks, I really appreciate it!
