Is it possible to pass a parameter to a callback function (I need to be able to use 'this' in my callback method )?

Here's my call (that isn't passing a parameter yet). I know I can make the callback function inline (and use a local variable that = this) but I call it all over so I'd rather not duplicate the code.

workOrders.load(
{
params: {
sessionID: sessionID,
resNum: num
},
callback: this.displayWorkOrders
});
