bootgrid change checkbox into radiobutton

I'm using jQuery-Bootgrid to create my tables. If I set rowSelect=true and multiSelect=falsethe checkbox can not be clicked (or checked).

I want to change the checkbox into a radiobutton if rowSelect=true and multiSelect=false. I don't know how to change this without editing the jquery.bootgrid.js file. Otherwise I don't know how to change this if I edit jquery.bootgrid.js.

The question is, how to :D
