I would suggest connecting your jotform SalesForce to see if it recognizes your new object (I presume that you mean fields).
Based on this forum post it seems that you should be able to do that: http://www.jotform.com/answers/93864-Feature-Request-Mapping-form-fields-to-the-Salesforce-cusom-fields
It is however best to try and please let us know if it is not working by any chance.
