How to pass additional variables to jqGrid formatter?

I'm trying to create some kind of reusable formatter for jqGrid column, I would like to create custom formatter where I'm able to pass additional data , something similar to this code:

function imageLinkFormatter(cellval,options,rowObject,icon,link_class,link_action){
     var img='<span class="ui-icon '+icon+' icon"><span/>';    
    var link='<a href="#'+link_action+'/id/'+rowObject.id+'" class="'+link_class+'" rel="'+rowObject.id+'">'+img+'</a>';
    return link;
    }
