knockout js showing related objects(selected id) on click - arrays

Question

I'm new to Knockout js and need some advice. What I am trying to do (the correct way) is have orders listed in a grid and a "production" button that when it is click, will show only the production objects that have matching id's to the order id. I'm trying to wrap my head around Knockouts binding, but I think I am over thinking things.
right now I have 2 objects Order and Production with are observable arrays filled with observables. Order has value of orderId and Production have value of prodId that I am checking for a match. I'm now wondering if I should not make this on object with mutli-dimensional array. Would it be easier to show selected data that way?
here is an example of the initial arrays
var initProduction = [
new Production({
proId:"183175",
pType:"Art TIme",
startTime:"11:20",
stopTime:"11:50",
totalTime:"",
by :"MJ"
})
var initData = [
new Order({
date:"06-09-2014",
orderId:"183175",
name:"Columbus Africentric",
dateRec:"05-23-2014",
rushDate:"",
totalQty:55,
parts:"1",
auto:"No",
type:"Local",
})
]
so should I combine into a multidimensional array? And if so, how would I do that? And how would I create a click event to show related data in another table showing only the production info.
I hope this makes sense and someone can help me. I apologize for my ignorance.
here is a stripped down version of my html bindings
<table>
<tbody data-bind="foreach:filteredOrders">
<tr>
<td>
<label class="read" data-bind="text:orderId, visible:true" />
</td>
<!-- controls -->
<td class="tools">
<button class="button toolButton" data-bind="click: $root.showSummary">Show Production</button>
</td>
</tr>
</tbody>
</table>
<h3>Production Summary</h3>
<table class="ko-grid" id="menu" >
<tbody data-bind="foreach:filteredProds">
<tr>
<td>
<div>
<label class="read" data-bind="text:proId, visible:true" />
</div>
</td>
</tr>
</tbody>
</table>

I would just have an orders array and then link the production object to the order.
var model = {
orders: [
{
date:"06-09-2014",
orderId:"183175",
name:"Columbus Africentric",
dateRec:"05-23-2014",
rushDate:"",
totalQty:55,
parts:"1",
auto:"No",
type:"Local",
production: {
proId:"183175",
pType:"Art TIme",
startTime:"11:20",
stopTime:"11:50",
totalTime:"",
by :"MJ"
}
},
{
date:"06-09-2014",
orderId:"183176",
name:"Angle Africentric",
dateRec:"05-23-2014",
rushDate:"",
totalQty:55,
parts:"1",
auto:"No",
type:"Local"
}
]
};
In the above json the second order doesn't have a production object.
Then in the viewModel I would use a computed which will return the orders depending on if all orders or only production orders should be shown. I've created a toggle here which is linked to the button.
var ViewModel = function (model) {
var self = this;
self.orders = $.map(model.orders, function (order) { return new Order (order); });
self.toggleProductionMode = function (order) {
order.showProductionOrder(!order.showProductionOrder());
};
};
var Order = function (order) {
var self = this;
ko.utils.extend(self, order);
self.showProductionOrder = ko.observable(false);
};
View:
<table>
<thead>
<tr>
<th>Id</th>
<th>Name</th>
</tr>
</thead>
<tbody data-bind="foreach: orders">
<tr>
<td data-bind="text: orderId"></td>
<td data-bind="text: name"></td>
<td data-bind="if: production"><button data-bind="click: $root.toggleProductionMode">Toggle Production Orders</button>
</td>
</tr>
<tr data-bind="visible: showProductionOrder, with: production">
<td colspan="3">
<table>
<tr>
<th>proId</th>
<th>pType</th>
</tr>
<tr>
<td data-bind="text:proId"></td>
<td data-bind="text:pType"></td>
</tr>
</table>
</td>
</tr>
</tbody>
</table>
