drilldown link in grid cell

[a197197]

I want to add a drilldown link to a few columns on grid.
Ideally I want to define the drilldown, be it url or js method, as a property of the column in column model, then I can use a generic link renderer to render all columns that have drilldown.
But the problem is the renderer function does not pass in the custom property I defined in column model. Is there a way to work arround this?
An alternative is to define a renderer function for each column that needs drilldown, but this seems to be an overkill as all drilldown columns only differ by the url or js method.

Any suggestions?
