Widget intermittently duplicating record updates

[chrisp1]

Hi, wonder if anyone can assist with a custom widget which is doing the ticket update in the server script twice, but only intermittently and I cannot understand what is going on. I'm new to development and have based the code on the many helpful community posts, so may well be flawed!

I've tried the widget in a fresh dev instance (with the custom field created) and witness the same there.

Widget code as below any assistance greatly appreciated...

thanks in advance chris

HTML
<div>
<div class="panel panel-primary b" >
  <div class="panel-heading">
    <h4 class="panel-title pull-left">      
           ${Test actions}      
       </h4>
    <div class="clearfix"></div>
  </div>
 <div class="panel-body"> 
 <button type="button" class="btn btn-success btn-block" ng-click="c.Chase('chase')" ng-disabled="clicked" >Request update</button> 
</div></div></div>

Client script
function ($uibModal, $scope, spUtil, spModal) {
 var c = this;
 $scope.$on('record.updated', function(name, data) {
  spUtil.update($scope);
 });

c.Chase = function(action) {   
  $scope.clicked = true;
  c.data.action = action;
  c.server.update().then(function() {
   c.data.action = undefined;
   spUtil.addInfoMessage("An update has been Requested", 3000);
   spUtil.update($scope);
  }); }      }

Server script
(function() {
 data.table = input.table || $sp.getParameter("table");
 data.sys_id = input.sys_id || $sp.getParameter("sys_id");

  var gr = new GlideRecord(data.table);
 if (!gr.isValid())
  return;

 if (!gr.get(data.sys_id))
  return;
 
 if (input && input.action) {
 var action = input.action;

 if (action === 'chase') {
  var cc = gr.u_chase_call_counter;
  gr.u_chase_call_counter = cc+1;
  gr.comments = "An update has been requested";
 // gr.setWorkflow(false);
  gr.update();
 }  } })();

I tried gr.setWorkflow(false); but this just stopped the comments being posted to the record, the u_chase_call_counter still updated once/twice.

Hi - i just removed the spUtil.update($scope); line from the end of the client script and replaced the one near the start with spUtil.refresh($scope); seems to be working fine now
