Array Collection not saving to database in manytomany relationship - mysql

Question

I have a many to many relationship using zend framework 2 and doctrine 2.
The relationship is between categories and products.
My products entity is
<?php

As can be seen the products and categories are linked through the table product_to_catagory.
I am using doctrines object multi checkbox to get the categories for the product using
$this->add(array(
'name' => 'categories',
'type' => 'Admin\DoctrineModule\Form\Element\ObjectMultiCheckbox',
'options' => array(
'label' => _('Categories:'),
'label_attributes' => array('class' => 'required'),
'object_manager' => $this->getEntityManager(),
'target_class' => 'Application\Entity\Categories',
'property' => 'category',
'is_method' => true,
'find_method' => array(
'name' => 'FindAll',
),
'disable_inarray_validator' => true,
),
));
The form is bound to the products entity
After the form is submitted the categories in the product entity returns Doctrine\Common\Collections\ArrayCollection
The problem I am having is that the categories are not being saved on the database in the product_to_catagory table when I flush the products entity.
Does anyone know what I am doing wrong?
Many thanks in advance.
EDIT
Changed owning side to products, code above updated.
