I think you don't have a clear "bigger picture" of all the pieces involved.
In order to update a component, you need to have it loaded somewhere you
know inside the page.
This mean that there will be a certain div with id "iwillreload" inside
your page that will point to the page that generates the grid.
In order to replace that component with a click on a link "outside" that
"iwillreload" component, you NEED to tell to the link where you want that
link to be loaded.
so, first of all, in your "main" page, you need to include a
LOAD(c='default', f='thegrid.load', ajax=True, target='iwillreload')
This will create a div with id iwillreload inside your page, with
default/thegrid.load called via ajax to fill this page "fragment".
To replace that component clicking on a link, with that link being the
source of the wanted "new fragment", you need to do
A('click this', callback=URL('default', 'thegrid.load',
vars=dict(something=else), user_signature=True), target="iwillreload")
i.e. you need to tell to A where would you want that url loaded.
