I recommend to create a directive

app.directive('customOnChange', [function() {
        'use strict';

        return {
            restrict: "A",

            scope: {
                handler: '&'
            },
            link: function(scope, element){

                element.change(function(event){
                    scope.$apply(function(){
                        var params = {event: event, el: element};
                        scope.handler({params: params});
                    });
                });
            }

        };
    }]);

this directive can be used many times, it uses its own scope and doesn't depend on parent scope. You can also give some params to handler function. Handler function will be called with scope object, that was active when you changed the input. $apply updates your model each time the change event is called
