How to update k-progress in a dialog?

Hi all,
I am building a panel-plugin and like to show the progress of determining Geo-Data.
Unfortenetly the k-progress bar won’t update, but a normal html-progress bar does,
by the same variable.
Any idea if i made a mistake or how i can update a ‘k-progress’ ui?

Update: same behavior, if i use k-progress outside k-dialog. no update :frowning:

Tnx in advance.

<k-dialog ref="dialogProgress">
    <template>
        ...
        <progress   :value="progress" max="100" />
        <k-progress :value="progress" />
        ...
    </template>
</k-dialog>

...
this.progress = Math.round(100 * this.stores/this.storesTotal);
...

i found a workaround by myself:

<k-dialog ref="dialogProgress">
    <template>
        ...
        <k-progress ref="dialogProgressBar" :value="progress" />
        ...
     </template>
</k-dialog>

...
this.$refs.dialogProgressBar.set(this.progress);
...

is that the way to go?
shouldn’t the initial value be reactive?
