Currently there is not a way to define a form with ng-submit within a dialog, and have the `<button type="submit">` within the actions.

Take for example this ui bootstrap modal example, where the parent elemint is a form.

```
<form name="formData" ng-submit="form.submit()" novalidate="novalidate">
  <div class="modal-header">

  </div>
  <div class="modal-body">
    <input type="text" required ng-model="name">
  </div>
  <div class="modal-footer">
    <button class="btn btn-primary"
            type="submit">
      OK
    </button>
    <button class="btn btn-warning" type="button" ng-click="cancel()">Cancel</button>
  </div>
</form>
```
