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]);
})();

You just need to set the ng-model to whatever it should be, so in this case you would set reportDetail.selectedLoc to whatever loc.dbid it should be.

For example: http://jsfiddle.net/uWLua/1/

Note: Make sure they have the same type, so in your example make sure they are either both integers, or both strings, it will not know they are the same if you have one as 5073 and one as "5073"

I updated the fiddle to show that the string and number do not do the same thing.
