Want to force the update of a binding because a non observable dependency has changed? KABOOM! Nastyness

// Force all properties bound to the price data binding to reevaluate
    function forceBindingRefresh(bindingName, element) {
        var bindings = $(element).data("bind");
        
        var koElement = ko.dataFor(element);
        
        if (bindings.indexOf(bindingName) >= 0) {

            // Lets split up the bindings so we can deal with each one
            bindings = bindings.split(",");
            $.each(bindings, function (index, value) {
                
                // Is this the binding we're looking for?
                if (value.indexOf(bindingName) >= 0) {
                    
                    // Let's find out what the valueAccessor for this binding is
                    var parts = value.split(":");
                    value = parts[1].trim().replace("()", "");

                    var observableToUpdate = koElement;
                    var propertyParts = value.split(".");

                    // The valueAccessor has dots in it? Let's find the end of this piece of string
                    $.each(propertyParts, function (ind, val) {
                        observableToUpdate = observableToUpdate[val];
                    });

                    // Ahh, almost there. I wonder if we can trick this observable into knowing it's changed.
                    if (observableToUpdate.valueHasMutated) {

                        if (observableToUpdate()) {
                            observableToUpdate.valueHasMutated();
                        }
                    }
                }
            });
        }
    }
