<attribute name="class">btn btn-primary btn-lg mt8 js_check_product a-submit disabled</attribute>
</t>
2)
<attribute name="class" t-if="product.qty_available > 0">btn btn-primary btn-lg mt8 js_check_product a-submit disabled</attribute>
3)
<attribute name="class" >product.qty_available > 0 and 'btn btn-primary btn-lg mt8 js_check_product a-submit' or 'btn btn-primary btn-lg mt8 js_check_product a-submit disabled'</attribute>
