How to bind events on dynamic generated buttons in backbone?

How do I bind click event on dynamic generated buttons in backbone.js?

 window.PackageView = Backbone.View.extend({

    tagName: "div",

    className: "package-template",

    events:{
      'click #display-nodes'  :  'main', // This button is declared in my HTML code and calls main method successfully.
      'click .display'        :  'disp', // This is dynamic button generated with class as display
    },

    getAction: function(nodeId){ // Get Actions from NodeId and generate buttons
      $('.nodes').append("<button>" + action.Name + "</button>"); //Generate Buttons
      $(".nodes button").addClass("display");
    },

    disp: function(){
        alert("Inside Disp Function");
    },

On clicking #display-nodes the nodes are displayed as required but .display is not working. How do I make this button call the function?
