ui.input().on('change',lambda:print(hello)) doesn't work

[v479038280]

I'm not sure if it's a bug,here is the code:

from nicegui import ui 

lbl=ui.label('hello')
input1=ui.input('input1').on('change',lambda e: lbl.set_text(e.value))
input2=ui.input('input2').on('input', lambda e: lbl.set_text(e.value))
input3=ui.input('input3',on_change=lambda e: lbl.set_text(e.value))  

ui.run()

only the input3 works fine ,input1 and input2 got the error:
AttributeError: 'GenericEventArguments' object has no attribute 'value'

and this version input4 doesn't work too

from nicegui import ui ,events

def onchange(e:events.ValueChangeEventArguments):
    lbl.set_text(e.value)
lbl=ui.label('hello')
input1=ui.input('input1').on('change',lambda e: lbl.set_text(e.value))
input2=ui.input('input2').on('input', lambda e: lbl.set_text(e.value))
input3=ui.input('input3',on_change=lambda e: lbl.set_text(e.value))  
inpu4=ui.input('input4').on('input', lambda e:onchange(e))

ui.run()

Hi @v479038280,

This is expected behavior. When registering to an event with .on(), the callback receives GenericEventArguments, which don't contain a value field.
