knockout error - Uncaught Error: Unable to parse bindings.

I get the following error when running my knockout code: Uncaught Error: Unable to parse bindings. Message: ReferenceError: measures is not defined; Bindings value: template: { name: 'measureDispTmpl', foreach: measures, as: 'food' }

You can see the jsfiddle code here:

http://jsfiddle.net/nickbuus/eUufc/

When I click the + icon I want the addMeasure method to be called - so that I can add a new measure to the current foodItem and save it. But when I try to call the addMeasure then the method: 

 self.addMeasure = function (myItem)

is never called and I get the above error.

I updated your fiddle. In your code you add a mesureItem in the foodList of the viewModel. That's why the food template doesn't work (because it tries to show an measure and a measure doesn't an measures property).

self.addMeasure = function (myItem) {
    var foodIte = self.selectedItem();
    var newItem = new MeasureItem();
    // mine 
    myItem.measures.push(newItem);
    self.selectedItem(newItem);
   // your :
   //self.list.push(newItem);
};

See fiddle

In response to your question :

Just add this at end of the addMeasure function:

self.selectedItem(newItem);

I hope it helps.
