Play (Animation) Widgets jslink not triggering the event

The Play widget event (and jslink binding) is working fine on IPYWidget's IntSlider. However, not working on Vue Slider. The manual mouse click event captures both Slider widgets. Am I missing anything?

import ipyvuetify as vue
import ipywidgets as widgets
from ipychart import Chart

import numpy as np

slider_type = 0  # IPYWidgets IntSlider
# slider_type = 1  # IPYVuetify Slider

def on_value_change(change, *args):
    cht.data = {
        "labels": [
            "One",
            "Two",
            "Three",
            "Four",
        ],
        "datasets": [{"data": np.random.random(4), "lineTension": 0.3}],
    }

cht = Chart(
    kind="line",
    data={
        "labels": [
            "One",
            "Two",
            "Three",
            "Four",
        ],
        "datasets": [{"data": np.random.random(4), "lineTension": 0.3}],
    },
)

play = widgets.Play(min=1, max=10, interval=1000)

if slider_type == 0:
    # IPYWidgets IntSlider
    slider = widgets.IntSlider(min=2, max=10, step=1, continuous_update=True)
    slider.observe(on_value_change, "value")
    widgets.jslink((play, "value"), (slider, "value"))
else:
    # IPYVuetify Slider
    slider = vue.Slider(
        v_model="value",
        thumb_label="always",
        min=2,
        max=10,
        step="1",
        label="Test",
        class_='ma-5, pa-5'
    )
    slider.on_event("change", on_value_change)
    widgets.jslink((play, "value"), (slider, "v_model"))

widgets.VBox([play, slider, widgets.VBox([cht])])

Start with the provided reproduction and compare the working ipywidgets IntSlider path with ipyvuetify's Slider event and v_model handling. Trace how jslink updates the Slider and how its change callback is registered; done means the linked Play widget updates the Slider and triggers the expected callback as the IntSlider does.
