angular-datatables Buttons disappearing on data change

Hello,

I’m using angular-datatables v0.5.1, along with the Buttons plugin, using the Angular data model way (datatable=“ng”), and when I change the data of the table - ‘Copy’, ‘Print’, ‘CSV’ buttons from the plugin just disappears.

            <div>
                <table id="node-table" datatable="ng" class="table table-striped"
                       dt-options="dtOptions" dt-instance="dtInstance">
                    <thead>
                    <tr>
                        <th ng-repeat="col in cols">{{col.title}}</th>
                    </tr>
                    </thead>
                    <tbody>
                    <tr>
                        <td>test</td>
                    </tr>
                    <tr ng-repeat="row in rows">
                        <td ng-repeat="col in cols">
                            {{row[col.field]}}
                        </td>
                    </tr>
                    </tbody>
                </table>
            </div>

Any changes to the rows scope variable, will rid of the Buttons.

My dtOptions as follows:

        $scope.dtOptions = DTOptionsBuilder.newOptions()
            .withPaginationType('full_numbers')
            .withBootstrap()
            .withButtons([
                'copy', 'colvis', 'csv', 'print']);

I also tried re-creating the dtOptions after the data change, but no luck there.

This isn’t a problem if i use dtColumns, and load data using promises.

Thanks, Otto

I have the same too. But I have found out a temporary solution to “keep” the buttons on screen. Like described in DataTables Buttons doc https://datatables.net/extensions/buttons/ under topic “Direct Insertion” we can insert the buttons directly, so we only need to put that code inside “drawCallback” event in datatable options so that the buttons are inserted each time the table is redrawn, like below:

Okay seems I wasn’t using one of the dev branch libraries, works fine with it. Hopefully gets merged to master soon then 😃 Many thanks!
