I've a table with a popover for every cell as in the follow example:

the call to popover:

```
<td ng-repeat="i in c.installments" ng-class="{ 'first' : i.first, 'last' : i.last, 'advance' : i.advance.value > 0, 'edited' : i.edited, 'final-installment' : i.last }" popover-trigger="{{ popoverFilter(i) }}" popover-placement="top" popover-title="{{i.id == 0 ? 'Advance' : 'Installment ' + i.id}}" popover-append-to-body="true" popover-template="popoverTemplate(i)" ng-init="payment= i; newpayment= i.amount.rounded_value" >

```

The popover template:

```
<script type="text/ng-template" id="editPopoverTemplate.html">
    <form name="editPayment">
      <h2>{{payment.amount.value|currency:undefined:cents}}</h2>
      <div class="form-group" ng-class="{ 'has-error' : editPayment.newpayment.$invalid }">
        <label>New value:</label>
        <input type="number" name="newpayment" ng-model="newpayment" class="form-control no-spinner" step="1" min="10" required>
        <span ng-messages="editPayment.newpayment.$error" class="help-block" role="alert">
          <span ng-message="required">The value is mandatory</span>
          <span ng-message="min">The value is too low</span>
          <span ng-message="max">The value is too hight</span>
        </span>
      </div>
      <div class="btn-group btn-group-justified" role="group">
        <div class="btn-group" role="group">
          <button class="btn" type="button">Cancel</button>
        </div>
        <div class="btn-group" role="group">
          <button class="btn btn-primary" type="button" ng-disabled="editPayment.$invalid">Save</button>
        </div>
      </div>
    </form>
  </script>

```

[working example on plunker](http://plnkr.co/edit/ArIDkkXs9Ev6ROBLSvDd?p=preview)

I need to close the popover via a "Cancel" button inside the popover.
It's possible? I need to extend the Angular UI Bootstrap library to do that?

Any help is appreciated.

The solution suggested in the linked answer close the popover when user click inside the popover, or outside the popover, but i need to close it by "close" button inside the popover.
