TestView = Backbone.View.extend({

trace: function(data) {
    console.log("ActionScript says: " + data);
}

});

function pageInit() {
testView = new TestView();
}

Using the global 'testView' you can call testView.trace from ActionScript

TestView = Backbone.View.extend({

el: $('#home'),

events: {
    "flashready": "trace"
},

trace: function(event, data) {
    console.log("ActionScript says: " + data);
}

});

new TestView();

function pageInit() {
console.log("pageInit");
//testView = new TestView();
}

function sendToJavaScript(value) {
$('#home').triggerHandler('flashready', value);
}

Call sendToJavaScript from ActionScript.
