Call to UI5 code diffrent

HI,

im having the following code and I want to call it different way but to do the exact same functionality

Path.addEventDelegate({
onAfterRendering: $.proxy(oController.onAfterPathField, oController)
},
Path);

I want also to add additionl code inside to debug it, I think that with function is the way but the following code is a bit confusing...

(oController.onAfterPathField, oController)

Thanks,

Stephane
