angularjs smart-table programmatically sort

I have a table set up using the smart-table plug in for AngularJS. Everything appears to work nicely. Rather than having the user click on the table header to trigger a sort, I'd like to programmatically trigger sorting from my Angular controller. I do not see a way of doing this in the documentation here:

Am I overlooking something?

Found this on JSFiddle, might help you: http://jsfiddle.net/vojtajina/js64b/14/

<script type="text/javascript" ng:autobind
src="http://code.angularjs.org/0.10.5/angular-0.10.5.js"></script>

<table ng:controller="SortableTableCtrl">
    <thead>
        <tr>
            <th ng:repeat="(i,th) in head" ng:class="selectedCls(i)" ng:click="changeSorting(i)">{{th}}</th>
        </tr>
    </thead>
    <tbody>
        <tr ng:repeat="row in body.$orderBy(sort.column, sort.descending)">
            <td>{{row.a}}</td>
            <td>{{row.b}}</td>
            <td>{{row.c}}</td> 
        </tr>
    </tbody>
