How to add dynamic events for view?

How can I add dynamic events in my view class in Backbone.js

I have a View Class with

var myViewClass = Backbone.View.extend({
    events: {
        'change select': 'changeSelect',
        'click a.changeLink': 'clearSelect'
    },

    initialize: function() {
        this.delegateEvents({'click select': 'changeSelect'});
    },

    .
    .
    .        
});

This is adding {'click select': 'changeSelect'} event, however somehow {'click a.changeLink': 'clearSelect'} doesn't woek.

anybody knows the solution?

Thanks, Rohan
