Thank you Alexander for the help. I tried using the template like you said but I am not sure once I submit the form with the grid what type of data I should expect my controller to receive. I am aware that if using the normal grid Save (transport-create) I will receive something like ArrayList<Map<String, Object>> models as the response body but this does not work when using the template like you suggested. I don't have a lot of experience with templates so I am attaching the JSP file so you could have a look at it. Please let me know what is wrong and what should be the arguments of my controller method that receives data from this form/grid.
Also, is it possible to use this grid to somehow work with the Spring <form:form> tag and submit the grid data as part of that form.
