As Ye Liu said, your controller calls your directive's compile and then link functions. From the angular directive doc (http://docs.angularjs.org/guide/directive):

The controller is instantiated before the pre-linking phase

The controller will be within the scope of your app, and once the post-link function finishes, your directive will be a child of this scope. Consider that the link function's purpose is to bind model data to your template and set watches for bound variables, not to create a discreet 'directive object'.

If you are trying to set the foo function inside of the link function in order to access directive scope variables, take a look at directive delegate functions and bound variables in the "scope:" directive attribute. The angular directive tutorial gives a somewhat obtuse version of this as its final example ("zippy"), and Angularjs Directive Delegate not firing through intermediary handler gives an example of a delegate function you can invoke from your template itself.
