I realised that Yii adds by some reason an event to ALL my links. No matter if I create them with Html::a or with pure html, the following event is always binded to the link:
The reason is that yii recognize data-method and data-confirm html attributes. This helps building links or actions with specifics http method and to display confirmation message, for example:
<a href='item/delete?id=1' data-method='post' data-confirm='do you realy want to delete'>Delete</a>
If your plugins don’t use thoose attributes, they should not be affected by this behaviour.
