How to access the angular filter value in node js

Question

I am trying to access the value in node js using req.body which is in ng-model, actually my ng-model is having a angular js filter,I need to get that filter value from the input field in node js using req.body, I paste my ng-model code snippet here, please help me to resolve

    <input type="disable" ng-disabled="true" class="form-control"
           name="count" ng-model="table.fields | mysum">

angular filter

app.filter('mysum', function() {
  return function(items) {
    var sum = 0;
    items.forEach(function(item) {
     if (item.item_count) {
         sum += item.item_count;      
      }     
    })
    return sum;
  }
})

You can't use ng-model with a filter -- ng-model needs to bind to property. — Explosion Pills

I think you should $watch for the model change and update the model value — Basilin Joe

This would be your DOM, you can't apply filters to ng-model.

<input type="disable" ng-disabled="true" class="form-control"
           name="count" ng-model="table.fields">

And in your controller code, do something like this. Inject $filter as dependency in your controller.

$scope.table = {};
$scope.table.fields = $filter('mySum')($scope.table.fields);

//watch for updated value... .
$scope.$watch('table.fields', function() {
    //watch for changes and do something... 
});
