The `vals` property is not updated when accessed through callback

[Plug11]

Description

The vals property is not updated when accessed through a callback (unlike other properties such as cols and rows).

This would be really useful to maintain state between updates to the data of the pivot table. Currently, vals always has the original value.

Steps/Code to Reproduce

Run the following code and change the quantity being plotted from "Total Bill" to "Tips". The output vals quantity will not change and will continue to report "Total Bill".

import dash
from dash.dependencies import Input, Output
import dash_html_components as html
import dash_pivottable

from data import data

app = dash.Dash(__name__)
app.title = 'My Dash example'

app.layout = html.Div([
    dash_pivottable.PivotTable(
        id='table',
        data=data,
        cols=['Day of Week'],
        colOrder="key_a_to_z",
        rows=['Party Size'],
        rowOrder="key_a_to_z",
        rendererName="Grouped Column Chart",
        aggregatorName="Average",
        vals=["Total Bill"],
        valueFilter={'Day of Week': {'Thursday': False}}
    ),
    html.Div(
        id='output'
    )
])


@app.callback(Output('output', 'children'),
              [Input('table', 'cols'),
               Input('table', 'rows'),
               Input('table', 'rowOrder'),
               Input('table', 'colOrder'),
               Input('table', 'aggregatorName'),
               Input('table', 'rendererName'),
               Input('table', 'vals')])
def display_props(cols, rows, row_order, col_order, aggregator, renderer, vals):
    return [
        html.P(str(cols), id='columns'),
        html.P(str(rows), id='rows'),
        html.P(str(row_order), id='row_order'),
        html.P(str(col_order), id='col_order'),
        html.P(str(aggregator), id='aggregator'),
        html.P(str(renderer), id='renderer'),
        html.P(str(vals), id='vals'),
    ]


if __name__ == '__main__':
    app.run_server(debug=True)
