Error encountered while attempting to perform date subtraction (Interpolation not supported)

Hey there, I created a basic function to subtract dates in JavaScript, but I keep getting an error.

Here is the JS code:

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

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

This is the error message displayed in the console:

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

Below is the snippet from the HTML view:

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

I have also attempted removing .getTime, which results in 'Invalid Date' being shown in the console.

Do you utilize the controllerAs syntax?

If not, simply mention the name of the function. However, if you are, make sure to include the controller name as a prefix.
