Using Angular 1.x I have two groups of select boxes, both call a function on change:

```
ng-click="checkOneOptionSelected()"

```

In my controller I would like to know which group of select boxes called the function:

```
$scope.checkOneOptionSelected = function(value){ 

      .. do something...

}

```

Is there a way to get the value of ng-model dynamically without passing a string as a parameter, perhaps using 'this' or similar. HArdcoding the value as a param will work but feels hacky?
