jQuery Grid Plugin - jqGrid

I have a form that needs to be submitted via ajax. I would like the response data of the form to populate a jqGrid. What would be the best way to do this? I'm currently making the ajax request using ajaxForm. I see that jqGrid supports making async calls, but I'm not sure how the async calls could be triggered via form submission and use the form data in the async request.

Thanks in advance for your help.
