Since I'm passing a function to another class method as a callback, I need to apply my function's this value as itself. I know there is some way using bind,call,apply but I want to set function's "this" value inside the function. Is there any way?

function CallBack(){
    this.setValue(...whatever);
    this.somekindofMethods(...whatever);
    !!Can I set "this" inside the function??
}
