Angular JS update input field after change

Question

I\'m trying to build a simple calculator in Angular in which I can override the total if I want. I have this part working but when I then go back to enter in a number in fields

Answer 1

Create a directive and put a watch on it.

app.directive("myApp", function(){
link:function(scope){

    function:getTotal(){
    ..do your maths here

    }
    scope.$watch('one', getTotals());
    scope.$watch('two', getTotals());
   }

})
