Error when subtract date (Can't interpolate)

Question

Hi i made a simple function to subtract dates, but i keeps giving me an error.

Code JS:

        $scope.tosum = function(d1, d2) {

        var d3 = new Date(d1.getTime() - d2.getTime());
        console.log(d3);
        return d3;
    };

Console Error:

Error: [$interpolate:interr] Can't interpolate: 
{{tosum(timesheet.startDate,timesheet.endDate )}}
TypeError: undefined is not a function

View/ html site :

  <tr data-ng-repeat="timesheet in timesheetsCtrl.timesheets | filter:searchText">
   <td>{{tosum(timesheet.startDate,timesheet.endDate )}}</td>

I also have tried without .getTime this gives 'Invalid Date' in console

If you log `d1` and `d2`, are you sure that those are properly defined dates and not some other type of object? — mgilson, Feb 05 '15 at 07:26
console.log('d1:' +d1+ ' - d2:'+ d2); output : d1:2015-02-02T23:00:00.000Z - d2:2015-02-04T15:16:01.416Z — Stweet, Feb 05 '15 at 07:36
on UI, it should `{{tosum(timesheet )}}` JS code `$scope.tosum = function(timesheet ) { var d3 = new Date(timesheet.startDate.getTime() - timesheet.endDate.getTime()); console.log(d3); return d3; };` — Pankaj Parkar, Feb 05 '15 at 07:51
@pankajparkar still gives Can't interpolate: {{tosum(timesheet)}} — Stweet, Feb 05 '15 at 08:29
`$scope.tosum` should be inside your controller..can you add your controller code to your question? — Pankaj Parkar, Feb 05 '15 at 08:51

Are you using controllerAs?

If you aren't, just write the name of the function, otherwise you'll need to prefix the controller name.

in same controller, changed to this.tosum = function(d1, d2) {..... {{timesheetsCtrl.tosum(timesheet.startDate,timesheet.endDate )}} but still same error – Stweet Feb 05 '15 at 08:31
