how's models loaded should be in MVC pattern?

Yes, Phil is right on all counts, but I figure I will add a little extra info to let you know why yours isn't working.

In a Model $this refers to the object Model, not to the main CI object that $this refers to in Controllers and Views. This drove me nuts when I was trying to update sessions from a Model for authentication purposes, and Phil's solution is the right one.
