Customize Minicart in Woothemes Canvas WordPress theme

Need to customize mini-cart in Woothemes Canvas theme to update without page refresh outside of shop loop. Currently using a custom Woocommerce script for product list display on front-end. When adding items to cart in this manner, the cart does not update until the user refreshes or loads a new page. There is an existing modal dialog that confirms the item was added to cart, but it does not update the mini cart at the same time. The correct behavior would be the success dialog box, and the mini cart would update without page refresh. Currently it works as expected within shop templates so this functionality is needed for pages outside the shop templates.
