JQuery, AJAX help.

[eluser]rschla104[/eluser]
Hello,

I'm converting a previous project to CI. The old pages were only php files where the logic and view resided in the same page. I've come across a section where $.ajax is being used to retrieve a JSON object(which is just an array of strings) and then run a callback function to parse the strings and get them ready to be placed into a dropdown as selectable options.

What would be the best practice for porting this functionality to CI and maintaining the MVC pattern? Would it belong in the model or the controller?
