Button delete doesn't display on selected rows

[androidovshchik]

Hi
There is a problem when i selected row/rows i didn't see the delete button

i found it's implementation
With {{ selectedCount }} Rows: <confirm-button label="Delete" activate="deleteRows ()" ck-class="btn-danger">

So a quick fix will be:
<button class="btn btn-danger" ng-click="deleteRows()">Delete</button>

But i cannot call a promt for user. It's sad. Please, fix this problem
