How can I get the 3 buttons in a single row in Bootstrap 3 ? The third button is going to the second row.

<div class="panel-footer">
    <div class="row" style="margin-right:0.5em;">
        <div class="col-md-offset-8">
            <button v-if="true" type="button" class="btn btn-primary pull-left" style="width: 48%">Save</button>
            <button v-if="false" type="button" class="btn btn-primary pull-left" style="width: 48%">Edit</button>
            <button type="button" class="btn btn-primary" style="width: 48%">Update</button>
            <a href="." class="btn btn-default pull-right" style="width: 48%">Cancel</a>
        </div>
    </div>
</div>
