Question

How is it possible to make knockout data-bind work on dynamically generated elements? For example, I insert a simple html select menu inside a div and want to populate options using the knockout options binding. This is what my code looks like:

$('#menu').html('<select name="list" data-bind="options: listItems"></select>');

but this method doesn’t work. Any ideas?

If you add this element on the fly after you have bound your viewmodel it will not be in the viewmodel and won’t update. You can do one of two things.

1. Add the element to the DOM and re-bind it by calling ko.applyBindings(); again
2. OR add the list to the DOM from the beginning and leave the options collection in your viewmodel empty. Knockout won’t render it until you add elements to options on the fly later.
