Calling a function in AngularJS service from the same service but within $watchcollection

Question

this is a follow up question to this topic: Calling a function in AngularJS service from the same service?

I realized too late I should open a new question instead asking it there (sorry for that)

I want to do the following: calling a function within a service function with the additional difficulty the call is within $watchCollection. It looks something like this:

return {

myFunc1: function(param) {

},

myFunc2: function(scope,param) {

    scope.$watchCollection(param,function(v) {

      return foo + this.myFunc1(param)// do some stuff with the first function 

    }       
}

} Because of function(v) { you are now in another function within the function and this is no longer the service but the window.

how can I get access to this myFunc1 within the myFunc2 $watchCollection parameter function?

thanks in advance

You can save the this in another variable (usually called self or that) and use it to access myFunc1.

myFunc1: function(param) {

},

myFunc2: function(scope,param) {

    var self = this;
    scope.$watchCollection(param,function(v) {

      return foo + self.myFunc1(param)// do some stuff with the first function 

    }       
}
