In AngularJs why does one scope variable update when changed, and another very similar variable does not?

around this issue There are actually a lot of things going in in your sample code at the same time, and I wasn't sure what part of the code was actually what you cared about, and what part was just for the demonstration.
Here's a working Plunkr: http://plnkr.co/edit/mjUtRSfFwYLGPC17O0st?p=preview
code :
return {
    items: [{Id: '1', Name: 'TestItem1'}, {Id: '2', Name: 'TestItem2'}],
    itemsById: {'1': {Id: '1', Name: 'TestItem1'}, '2': {Id: '2', Name: 'TestItem2'} },
}
itemsById[itemUpdate.Id] = itemUpdate;
var myItem = ThatService.itemsById[123];
myCollection[Id] = myCollection[Id] || {};
angular.extend(myCollection[Id], myNewData);

it helps some times In your deleteProperty method, you are just setting the property parameter to null and this is never going to have any effect on your scope.
A simplified example of what you're doing here is:
code :
$scope.zoo = { id: 1, name: 'Lorem' };
var property = $scope.zoo;
property = null;
console.log($scope.zoo);  // previous line had no effect on $scope.zoo
$scope.deleteProperty = function(property) {
   delete $scope[property];
};
<a ng-click="deleteProperty('zoo')" class="remove icon-remove"
   title="Remove"></a>
$scope.deleteProperty = function(property) {
   for (var p in $scope) {
       if ($scope.hasOwnProperty(p) && $scope[p] === property) {
           delete $scope[p];
       }
   }
};

help you fix your problem The watch needs to include an additional boolean true value on the watch to perform a deep comparison.
code :
     $scope.$watch('search', (o, n) => {

        // this watch only get's called once, and never again.

        this.$log.log(`watch called ${JSON.stringify(o)} :: ${JSON.stringify(n)}`);
        if (n) {
            this.$log.log(`watch updating ${JSON.stringify(n)}`);                    

            // it turns out the below code is not necessary, but
            // it only gets' called once, even when the value changes.
            $scope.searchTextBox = n;
        }
    }, true); // the true is necessary

like below fixes the issue You should use the two-way data binding.
In your directive, you can specify an isolate scope, and use the = syntax, which is pretty useful.
