title: How can I add qty for custom option before adding product to cart
body: <p>I want to create a functionality to add qty for each individual custom option. For example I have to create a basket and there I want to add 2 apple, 3 quinces, 1 melon.</p>
  
  <p>After the help of <strong>Ashlesha</strong> I've manage to have something very good. Right now I have another problem that pops out from this one. I've done the change on Check box because I want to configure the product with check boxes and add quantity on every one. </p>
  
  <p>Question: How can I auto update the price and quantity after I do this? (on product page and then pass it to checkout)</p>
  
  <pre><code>&lt;span class="label"&gt;
      &lt;label for="bundle-option-&lt;?php echo $_option-&gt;getId() ?&gt;-&lt;?php echo $_selection-&gt;getSelectionId() ?&gt;"&gt;
          &lt;?php echo $this-&gt;getSelectionQtyTitlePrice($_selection) ?&gt; 
      &lt;/label&gt;
  
      &lt;input &lt;?php if (!$_canChangeQty) echo '' ?&gt; id="bundle-option-&lt;?php echo $_option-&gt;getId() ?&gt;-qty-input" class="input-text qty&lt;?php if (!$_canChangeQty) echo '' ?&gt;" type="text" name="bundle_option_qty[&lt;?php echo $_option-&gt;getId() ?&gt;]" value="&lt;?php echo $_defaultQty ?&gt;" onclick="bundle.changeSelection(this)"/&gt;&lt;/span&gt;
  </code></pre>
