Hello,

I am trying to add an event on tags of many2many fields if form is in edit mode. For that I have written below code:

var FieldMany2ManyTags = relationalField.FieldMany2ManyTags.extend({
events: _.extend({}, FieldMany2ManyTags.prototype.events, {
'click .o_tag_color_0': '_onClickTag',
}),

_onClickTag: function(events){
console.log('Test');
alert('many2many tag');
},

But click on tags click event is not call. It give me following error on inspect console as:

TypeError: Cannot read property 'prototype' of undefined

 I am doing somthing wrong?  Any alternative way is available for the same

Thanks In advance.
