The fundamental issue here is the difference between an AJAX call from within JavaScript and a regular web request. From the server's perspective, there isn't much of a difference. It's just how the browser handles those.

Your Create action is set up to be used by an AJAX call, which you're doing. That's all well and good. But I assume that Index is not. That one expects to be a regular request. As I said, from the server's perspective, there really isn't a difference. So, as you've observed, the call to Index happens just fine. It just doesn't "render" in the browser.

The terminology is a little mixed up here. You don't want to "render the view with jQuery," you want to direct the browser to make that request. When should this happen? I'm assuming that you want this redirect to take place perhaps after the success in your AJAX call?

If you want your JavaScript to redirect, then you're on the right track. Just approach it differently. jQuery doesn't call the Index view in an AJAX manner (because it wouldn't know what to do with the response). Simply use a JavaScript call to redirect the user to another resource:

window.location.href = "http://yourserver/controller/action/etc";
