ServiceNow spUtil - angularjs

Question

I'm trying to make a slight improvement to an existing widget that our team created, but can't seem to get it to work correctly. We have a widget that does a RowCount of tasks and groups them by state. I want the RowCount to auto update once a task is complete without having the user press the refresh button. I've read some documentation on $rootscope, $broadcast, and $on, but can't seem to get it to work.
Below is snippet of our HTML:
<table class="table table-sm table-responsive">
<tbody>
<tr class="h3">
<td colspan=2>Complete</td>
</tr>
<tr class="h2 bg-success" ng-repeat="x in data.values track by $index">
<td><span class="glyphicon glyphicon-check"></span></td>
<td>{{x.completedCount}}</td>
</tr>
</tbody>
</table>
A snippet of our Server Script:
var values = [];
var _completedCount;
var gsCompleted = new GlideRecordSecure('sn_hr_core_task');
//CLOSED COMPLETE, CLOSED INCOMPLETE,
gsCompleted.addQuery('state', 'IN', '3,4,7');
gsCompleted.addQuery('assigned_to', gs.getUserID());
gsCompleted.addQuery("parent.state", 'NOT IN', '1,800,900');
gsCompleted.query();
if(gsCompleted){
_completedCount = gsCompleted.getRowCount();
}
else{
_completedCount = 0;
}
values.push(
{
completedCount: _completedCount
});
data.values = values;
How do I get this widget to auto update the Completed row count without refreshing the page? I've been playing around with spUtil recordWatch, but cannot get it to work correctly:
function($scope, $sce, spUtil) {
var c = this;
c.data.loading = true;
//After page initially loads re-call server script to load data
c.server.get({
action: 'retrieve_data'
}).then(function(response) {
c.data.loading = false;
console.log('Response');
console.log(response);
c.data.values = response.data.values;
spUtil.recordWatch($scope, 'sn_hr_core_task', "", function(name,data) {
spUtil.update($scope);
})
});
}

Take a look at the widget Simple List, it has an example of one that may help a bit.
You should be able to change your recordWatch to this
var filter = "stateIN3,4,7^parent.stateNOT IN1,800,900^assigned_to=" + window.NOW.user_id;
spUtil.recordWatch($scope, 'sn_hr_core_task', filter);
You generally won't need a callback function unless there is some specific action you're triggering.
