breeze doesn't recognize the modified entity

I have a breeze implementation where it takes a location object and displays the properties on the UI. I do a change to a few properties and try to save the changes, but breeze doesn't recognized the entity as changed. Following is my code:

    [HttpGet]
    [CustomAuthorize(Claims = "permission:CanViewLocationAttributes")]
    public Location GetLocationById(int clientId, int locationId)
    {
        //returns a single Location object

    }

Following is my client-side functionality to retrieve the entity and save the entity:

    function getLocationById(clientId, locationId) {
        var self = this;

        return EntityQuery.from('GetLocationById')
                            .withParameters({ clientId: clientId, locationId : locationId })
                            .using(self.manager)
                            .execute()
                            .then(querySucceeded, this._queryFailed);

        function querySucceeded(data) {
            if (data.results.length > 0) {
                return data.results[0];
            }
            logSuccess(localize.getLocalizedString('_RetrievedLocations_'), locations, true);
        }
    }

        function saveLocationSettings(clientId) {
        var self = this;
        var saveOptions = this.manager.saveOptions.using({ resourceName: "SaveLocationSettings",  allowConcurrentSaves: true });
        var entitiesToSave = self.manager.getChanges();
        return self.manager.saveChanges(entitiesToSave, saveOptions).then(saveSucceeded, saveFailed);
    }

my problem is that here the value of entitiesToSave is 0, even after I make changes to the fields in UI and save them.

Following is how I bind the entity to my angular model:

  function getLocationDetails() {
        clientcontext.location.getLocationById($route.current.params.clientId, $route.current.params.id)
  .then(function (data) {
      basicLocationSettings.id = data.locationId;
      basicLocationSettings.parent = data.fkParentLocationId;
      basicLocationSettings.locationType = data.locationType;
      basicLocationSettings.locationName = data.locationName;
      basicLocationSettings.locationDisplayName = data.locationDisplayName;
      basicLocationSettings.locationCode = data.locationCode;
      basicLocationSettings.isActive = data.activeStatus;
      basicLocationSettings.timeZone = data.fkTimeZoneId;
      basicLocationSettings.usesAppointments = data.usesAppointments;
      basicLocationSettings.availabilityWindowDays = data.availabilityWindowDays;
      basicLocationSettings.appointmentCutOffDays = data.appointmentCutOffDays;
      basicLocationSettings.dailySummaryEmailTime = data.dailySummaryEmailTime;
      basicLocationSettings.reminderBeforeApptEmailTime = data.reminderBeforeApptEmailTime;
      basicLocationSettings.saveLocationSettings = function () {
          clientcontext.location.saveLocationSettings($route.current.params.clientId);
      }
  });
    }

Can anyone explain what I'm doing wrong? This is my first attempt on breeze and I'm kind of stuck here.

I modified my code as follows and now the save is working:

 function getLocationById(clientId, locationId) {
        var self = this;
        var location = null;

        return EntityQuery.from('GetLocationById')
                            .withParameters({ clientId: clientId, locationId : locationId })
                            .using(self.manager)
                            .execute()
                            .then(querySucceeded, this._queryFailed);

        function querySucceeded(data) {
            if (data.results.length > 0) {
                location = data.results[0];
            }
            logSuccess(localize.getLocalizedString('_RetrievedLocations_'), locations, true);
            return location;
        }
    }

Note that I'm returning a location object, and in my controller, I bind the location object to my POJO.

        function getLocationDetails() {
        clientcontext.location.getLocationById($route.current.params.clientId, $route.current.params.id)
  .then(function (data) {
      basicLocationSettings.location = data;
      basicLocationSettings.saveLocationSettings = saveLocationSettings;
  });
    }

Now when I call saveChanges(), I pass the location object to the repository:

      function saveLocationSettings() {
        clientcontext.location.saveLocationSettings(basicLocationSettings.location);
    }

It looks like you are copying the breeze location entity's property values into an pojo object variable named "basicLocationSettings". Any changes to basicLocationSettings will not be tracked by the breeze entity manager or reflected in the source breeze entity. You'll need to bind the actual breeze entity to your UI so that user data entry modifies the entity property values directly.
