How to programmatically select ng-option value?

Question

I have a view that is filled with dropdownlists to filter a report. I also have a view of saved filters that are displayed as links. When a user clicks on their saved filters, I want the appropriate values of the dropdownlists to be selected. The drop downs are being populated properly. On the saved filter link there is an ng-click that will call a function that iterates through the collection of saved filter values and automatically selects the correct one. I cannot figure out how to programmatically set the selected option. Any help is much appreciated!

<select uid="locSelect" 
        class="span12" 
        ng-model="reportDetail.selectedLoc" 
        ng-options="loc.dbid as loc.serviceName for loc in reportDetail.locList | orderBy:'name'">
    <option uid="unselectedLocOption" value="">-- Select One --</option>
</select>

Here is the list of saved filters:

<div class=" well fixed-search" style="overflow-x: hidden;overflow-y: auto;">
<div class="well-header">
    Saved Filters
</div>
<div ng-if="!hasSavedFilters">
    <span>No saved filters</span>
</div>
<ul ng-if="hasSavedFilters" class="nav nav-list dashboard-list">
    <li ng-repeat="filter in reportDetail.savedFilters">
        <a uid="savedFilter" href="" ng-click="reportDetail.loadSavedFilters(filter.filters)">
            <span ng-bind="filter.title"></span>
        </a>
    </li>
</ul>

And here is my controller

(function(){
'use strict';

var ReportDetailController = function(ReportsService, $scope){
    var _locList = {};
    var _hospitalStatusList = {};
    var _providerStatusList = {};
    var _savedFilters = [];
    var _sourceTypeList = {};
    var _dateRangeList = {};

    var _init = function(){
        ReportsService.getCurrentReportSavedFilters().then(function(data){
            $scope.reportDetail.savedFilters =data;
            $scope.hasSavedFilters = ReportsService.hasSavedFilters();
        });

        ReportsService.getLOCListForDDL().then(function(data){
            $scope.reportDetail.locList = data;
            //$scope.reportDetail.selectedLoc = $scope.reportDetail.locList[0];
        });

        ReportsService.getSelectListData()
            .then(function(data){
                $scope.reportDetail.sourceTypeList = data.CONNECTION_TARGET_STATUS;
                $scope.reportDetail.hospitalStatusList = data.CONNECTION_SOURCE_STATUS;
            });
        ReportsService.getDateRangesForDDL()
            .then(function(data){
                $scope.reportDetail.dateRangeList = data;
            });

        $scope.reportDetail.providerStatusList = ReportsService.getProviderStatusForDDL();


    };



    var _loadSavedFilters = function(filters){
        for(var i = 0, l = $scope.reportDetail.locList.length; i<l; i++){
            if($scope.reportDetail.locList[i].serviceName == filters.levelOfCare){
                 $scope.reportDetail.selectedLoc = $scope.reportDetail.locList[i];
                console.log($scope.reportDetail.selectedLoc);
            }
        }
    }

    var _isActive = function(filter){
        for(var i = 0, l = $scope.reportDetail.savedFilters.length; i<l; i++){
            if(filter.title == $scope.reportDetail.savedFilters[i].title){
                return true;
            }
            return false;
        }
    }

    var _generateReport = function(){
        return ReportsService.generateReport();
    };

    $scope.reportDetail = {
        init: _init,
        selectedLoc: null,
        isActive: _isActive,
        locList: _locList,
        selectedHospitalStatus: 'NOTIFIED',
        hospitalStatusList: _hospitalStatusList,
        selectedProviderStatus: 'NEW',
        providerStatusList: _providerStatusList,
        selectedSourceType: 'CONNECTED',
        sourceTypeList: _sourceTypeList,
        selectedDateRange: '',
        dateRangeList: _dateRangeList,
        savedFilters: _savedFilters,
        loadSavedFilters: _loadSavedFilters,
        generateReport: _generateReport
    };

    $scope.reportDetail.init();
};

app.controller('ReportDetailController', ['ReportsService', '$scope',  ReportDetailController]);
})();

Due to time constraints I ended up going a different route. I created an event bus of sorts in my service layer and subscribe to the even in my controller, updating the model, and used ng-repeat with ng-selected.

I'm still interested to understand why this was not working with ng-options. The model and ng-options types matched, and everything appeared to be wired up correctly. When I have more time i'll re-address the original issue. Thanks for all who responded!
