Bound async method not working: AttributeError: 'App' object has no attribute '_depends'

[MarcSkovMadsen]

I'm on the current main branch.

import asyncio

import param

import panel as pn

class App(param.Parameterized):
    run = param.Event()
    clicks = param.Integer(-1)

    @pn.depends("run")
    async def click_view(self):
        self.clicks+=1
        await asyncio.sleep(0.5)
        return f"Clicked {self.clicks} times"

app=App()
pn.Column(app.param.run, app.click_view).servable()

AttributeError: 'App' object has no attribute '_depends'

If I change the click_view method to a function It does not raise an exception, BUT it does not display the value either.

import param

import panel as pn

class App(param.Parameterized):
    run = param.Event()
    clicks = param.Integer(-1)

app=App()

@pn.depends(app.param.run)
async def click_view(_):
    app.clicks+=1
    return f"Clicked {app.clicks} times"

pn.Column(app.param.run, click_view).servable()
