Form script allows you to perform operations before the form is rendered , or to attach data model elements to get notifications. Form script also has some library functions like $Xml depending on the context. Please refer to the side bar for available library functions and scripting reference.

Form script also has a the following $Form variable with the following properties:

$Form = {
  element : $('form'),       // jQuery form element
  refresh : function() {}    // method to re-build and render form from the scratch
  readonly : boolean,        // Specifies whether the form is in readonly or in edit mode
}

...

Attach a model element to an existing data . 

$Xml.Bind('Person/Name', function() {
   // executed when Person/Name is changed
});

For example, Bind method does not work for list items that are not yet created. If you want to attach nodes for the future elements you can use $Xml.Live method.
