I am not sure if it’s a bug or something else, but it looks so strange that I am totally confused.
Please see the image below, the title of the note #note_title has value 3333 as in Firebug, but it is shown 44444 in the webpage, and in the console, from jQuery, the value of the title is also 44444, Why is that?

The value attribute specifies the default value.
The value property (which
val()accesses) and the UI show the current value.
