where 

categoryValue = $("#category option:selected")[0].innerHTML

But when i am creating the entity like 

XrmServiceToolkit.Soap.Create(entity)

Answer 1

When trying to assign option set values using XrmServiceToolkit, which new_category does look like it is, you need to assign the value like so:

entity.attributes["new_category"] = { value: categoryValue, type: "OptionSetValue" };
