I am able to launch my Flow is a SLDS modal but when I click on the Flow's NEXT button, the entire VF page is re-rendered. How can I make the NEXT button function properly?

// Mike Modal methods
        function openModal2() {
        console.log('running openModal2');
            j$("#modalWizDiv").addClass('slds-modal--large');
            j$("#modalWizDiv").addClass('slds-fade-in-open');
            j$("#modalWizDivBackDrop").addClass('slds-backdrop--open');
            j$("#modalWizLoading").addClass('slds-hide');
            j$(".modalWizSubmit").click(function(event) {
            console.log('running in event')
            closeWizModal();
            });
