Few questions:

Is it possible to call a controller method in a helper module (e.g., application helper)?
If so, how does the helper handle the rendering of views? Ignore it?
In what instances would you want to call a controller method from a helper? Is it bad practice?
Do you have any sample code where you're calling controller methods in helper?
