you first need to make changes in com.gargoylesoftware.htmlunit.javascript.host.Form to add js setter and getter for 
onsubmit like what is done in com.gargoylesoftware.htmlunit.javascript.host.HTMLElement for different event handlers. 
Then you have to get this javascript function called in place of the interpretation of the string attribute when the 
form is submitted. All these changes can be done with current architecture of htmlunit.
