Change event on select with knockout binding, how can I know if it is a real change?

Question

I am building a permissions UI, I have a list of permissions with a select list next to each permission. The permissions are represented by an observable array of objects which

Answer 1

Quick and dirty, utilizing a simple flag:

var bindingsApplied = false;

var ViewModel = function() {
    // ...

    this.permissionChanged = function() {
        // ignore, if flag not set
        if (!flag) return;

        // ...
    };
};

ko.applyBindings(new ViewModel());
bindingsApplied = true; // done with the initial population, set flag to true

If this doesn't work, try wrapping the last line in a setTimeout() - events are async, so maybe the last one is still pending when applyBindings() already returned.
