Bootstrap DotVVM GridView的问题

Question

我在bootstrap表中有以下代码：

<bs:GridView DataSource="{value: TablaGridView}" SortChanged="{command: OrdenaTabla}" class="table table-striped table-bordered table-hover table-full-width">
    <Columns>
        <dot:GridViewTextColumn HeaderText="Nombre" ValueBinding="{value: Nombre}" AllowSorting="True" />
        <dot:GridViewTextColumn HeaderText="Apellido Paterno" ValueBinding="{value: ApellidoPaterno}" AllowSorting="True" />
        <dot:GridViewTextColumn HeaderText="Apellido Materno" ValueBinding="{value: ApellidoMaterno}" AllowSorting="True" />
        <dot:GridViewTextColumn HeaderText="Estado" ValueBinding="{value: Estado}" AllowSorting="True" />
        <dot:GridViewTextColumn HeaderText="RFC" ValueBinding="{value: RFC}" AllowSorting="True" />
        <dot:GridViewTemplateColumn AllowSorting="false">
            <ContentTemplate>
                <dot:Button ButtonTagName="button" class="btn btn-blue show-sv" href="#FormaCliente" data-startFrom="right" Click="{command: _parent.Edit(_this)}">
                    <i class="fa fa-edit"></i> Editar
                </dot:Button>
                &nbsp;&nbsp;&nbsp;
                <dot:Button ButtonTagName="button" class="btn btn-red" Click="{command: _parent.Delete(_this)}">
                    <i class="fa fa-trash-o"></i> Borrar
                </dot:Button>
            </ContentTemplate>
        </dot:GridViewTemplateColumn>
    </Columns>
</bs:GridView>

在模板中我有两个按钮，它们将打开一个表格来编辑表格中的数据。但我有问题，按钮没有执行网格内的动作。如果我把按钮放在网格外面执行动作，但是网格内部什么都不做。你可以帮我解决这个问题。
