Why is $(this.TabElement).kendoTabStrip(config).data('kendoTabStrip') undefined?

Hello,

I'm using LitElement to create a reusable tab component, but when I 'm initializing the kendoTabStrip, the TabStrip property is undefined.

In my firstUpdated function I'm setting the TabElement property:

    firstUpdated (changedProperties) {
        this.TabElement = this.shadowRoot.querySelector('#tabs-container')
    }

In the parent element, I'm setting the TabConfig property:

    setHtml () {
        const tabs = this.shadowRoot.querySelector('tabs')
       tabs.TabConfig = TabConfig(this)
    }

I have a setter in the tabs component that addsTabs after being set:

    set TabConfig (value) {
        const oldValue = this._TabConfig
        this._TabConfig = value
        const self = value.self
        this.addTabs(self, oldValue)
    }

I'm initializing the kendoabStrip using the previously set properties (all properties are defined):

    addTabs () {
        this.TabStrip = $(this.TabElement).kendoTabStrip(this.TabConfig).data('kendoTabStrip')

        this.TabConfig.tabs.forEach(tab => {
            if (tab.show) {
                this.TabStrip.append(tab) // This throws an error "Cannot read property append of undefined"
            }
        })
    }

I tried initializing the TabStrip property in the setter for the TabConfig, but ended up with the same result. Any idea as to why this.TabStrip is undefined?
