basic ajax using CI

[eluser]omgnoseat[/eluser]
I have a slightly different question. I already know how to fetch data with ajax, I just don't know whats the best way to pass it to the view.
I have the following situation:

Javascript->calls a controller function with ajax
controller -> calls model to retrieve database info
model-> passes data back to controller as an array
-> controller receives data, needs to send data to the view (without a page reload of course)

Now I could just format all the data in the controller and put the data inside a div using javascript. but that seems very sloppy.
Is there any good way for this? I'm handling quite large amounts of data (blog posts) and don't know how to effectivly handle this.

Thanks in advance
