Autoload a model and run a function?

[eluser]chefnelone[/eluser]
Hello,

Is there any way to autoload a model and autorun a function (which is inside that model)

I have all the texts of my site storaged in a database, then regardless which page of the site is loading I need to recover those texts from the data base.

I think the best way to do this is to autoload a model run a function and fetch all the texts. Then I'd save them in a Session variable to access it whenever I need it.

I know I can autoload a model but not how to autorun a function, if possible.
If not, what can I do?
