durandal knockout data-binding?

[Shaunt Kojabashian]

Anyone else ever have issues where knockout doesn't seem to be doing a 2-way data-bind?

I've got a text field i'm making changes to and trying to capture the value after a button click and the new value doesn't seem to be changing...

I've dumbed this down but still seems like it's not doing what I want.

//summary.js

define(function (require) {

    var system = require('durandal/system');

    var app = require('durandal/app');

                    

    var self = this;    

    

    self.dueStart = ko.observable();

    self.dueEnd = ko.observable();    

    self.testData = function () {      

        system.log(self.dueStart());        

    };

    return {

        activate : function(context) {           

            self.dueStart('12/1/2012');

            return true;    

        }        

    };

});

//summary.html

<input id="dueStart" name="dueStart" type="text" data-bind="text : dueStart" /> 

<button data-bind="click: testData">Filter</button> 

if I change the contents of the textbox "dueStart" and click filter... the functoin runs, yet the system.log still returns 12/1/2012... data hasn't changed at all...

something seems screwy... any ideas?

Use the value binding and not the text binding, fell into this trap myself before :)
