backbone.js view event does not execute
===

I have the following backbone.js view shown below. It was working fine, and now the click event does not execute when the form button is clicked. No errors in console, or any other obvious signs of why is shown.

    window.FormOptionView = Backbone.View.extend({
        template: _.template($('#test-option').html()),
        render: function (eventName) {
            $('#test1').append(this.template(this.model.toJSON()));
             $('#test2').append(this.template(this.model.toJSON()));
            return this;
        }
       
    });
    
    
    window.AddTestView = Backbone.View.extend({
        
    template: _.template($('#test-add').html()),
    
    initialize: function () {
        this.collection.bind("reset", this.render, this);
        this.render();
        			
    },
    
    events: {
                 "click button": "addTest" 
    },
    
    addTest: function(event){
    		event.preventDefault();
    		var test = new Test({
    		    test1: {
    		        firstName: $("#test1 option:selected").val(),
    		        lastName: $("#test1Score").val()
    		    },
    		    test2: {
    		        firstName: $("#test2 option:selected").val(),
    		        lastName: $("#test2Score").val()
    		    }
    		});
    		
    		test.add(result);
    		app.navigate("tests", true);
    		
    },
     
    render: function (eventName) {
    	$('#content').html(this.template());
        _.each(this.collection.models, function (test) {
        	 this.renderSelectBox(test);
         }, this);
        return this;
    },
    
    renderSelectBox: function (item) {
           var optionView = new FormOptionView({
               model: item
           });
           $(this.el).append(optionView.render().el);
       }
    });
