I want to add a product, find the node an let it flash products = observableArray([]); new_product = new Product(); products.push(new_product); $("tr", new_product.elements).flash(); I tried using afterAdd but it flashed each time I added something. I need to flash only with one of my adding function. The other functions which add should not flash the element. NOTE: flash is a custom JQuery function
