javascript remoting doesn't work asynchronously

I'm trying to create some html elements as a reponse to a button click in my visualforce page, and i am using javascript remoting, but no matter what i do the page keeps refreshing after the button click.
my visualforce page:
<apex:page Controller="BpmIcountPayment">
    <script src="https://code.jquery.com/jquery-1.12.4.js"></script>
      <script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.12.1/jquery-ui.css"/>

    function addProductRow(e) {
        var productId = $('select[id$=productsLov]').val();
        function(result, event) {
            if  (event.status) {
                productRowHtml = '<div id="p-' + result.Id + '">';
                productRowHtml += '<span>' + result.Description + '<span>';
                productRowHtml += '<button class="plusButton">+</button><input type="number">1</input><button class="minusButton">-</button>';
                if (result.Name == 'discount') {
                    productRowHtml += '<input classtype="number"></input><span>₪</span>';
                productRowHtml += '<span>' + result.Price + '₪</span>';
            } else if (event.type === 'exception') {
                console.log(event.message + '   ' + event.where);
            } else {
                console.log('else   ' + event.message);
        }, {escape: true});

<apex:form >
    <apex:selectList id="productsLov" value="{!productsTitle}" multiselect="false" size="1">
        <apex:selectOptions value="{!ProductsLov}"></apex:selectOptions>
    <button id="addProductButton" onclick="addProductRow()" reRender="false">add product</button>
<div id="productsRows">

I even managed to print the result into the console, but it does so after refreshing the page.
my controller:

public class BpmIcountPayment{

private final Account account;

public String productsTitle {
  get { return 'products'; }

public List<Product2> productsList {
  get { return productsList; }
  set { productsList = value; }

public BpmIcountPayment() {
    account = [SELECT Id, Name, Site FROM Account
               WHERE Id = :ApexPages.currentPage().getParameters().get('id')];

public Account getAccount() {
    return account;

public static Product2 getProductRowData(string productId) {
    Product2 product = [SELECT Id, Name, Family, Price__c, Description 
                        FROM Product2 
                        WHERE Id = :productId];

    return product;

public List<SelectOption> getProductsLov() {
    List<SelectOption> products = new List<SelectOption>();
    productsList = [SELECT Id, Name, Family, Price__c, Description 
                    FROM Product2 
                    WHERE (Family = 'ShopProduct') 
                    OR (Family = 'CourseParent') 
                    OR (Family = 'SFCourseProgram')];

    for (Product2 currProduct : productsList) {
        products.add(new SelectOption(currProduct.Id, currProduct.Name));

    return products;

I found the issue! It was just a case of defining the button type as "button" because the default was "submit" and that caused the page to re-render
