mui-datatables: Count option is not refreshed Server side rendering V2.1.0

I’ve got some issues with count options with server side rendering. Count is not updated when I update my options parameter.

1. Count is initialized with 0 in first render
2. Then count is fetch with async method
3. Options is updated with right count
4. MuiDatatable is not refresh (as options is setup in componentWillMount method) It uses only number of element of my data array

async componentDidMount() {
        // Start fetching data
        manufacturersCollection.fetch();
        const value = await phonesCollection.fetchCount(this.componentName)
        runInAction(() => this.count = value);
        phonesCollection.fetch({data: {category: this.componentName, page: 0}});
        const navigationData = this.props.location.navigationData;
        NavigationUtils.showNavigationMessage(navigationData, this.snackBar);
    }

// Prepare data from collection Transform list of object to simple array with order
    @computed
    get preparedData() {
        return DataTableUtils.createDataArray(phonesCollection, this.columns);
    }
render() {
        
        const {classes, breadcrumbs} = this.props;
        
     // Options for basic grid
        // TODO: Options in custom component
        const options = { selectableRows: false,
                        serverSide: true,
                        count: this.count,
                        download: true,
                        print: false,
                        viewColumns: false,
                        responsive: "scroll",
                        filterType: 'dropdown',
                        rowsPerPage: 15,
                        onTableChange: (action, tableState) => {
                            switch (action) {
                            case 'changeRowsPerPage':
                            case 'changePage':
                                phonesCollection.fetch({data: {category: this.componentName, page: tableState.page, size: tableState.rowsPerPage}});
                              break;
                            case 'search':
                                if(tableState.searchText && tableState.searchText.length > 1) {
                                    phonesCollection.fetch({data: {category: this.componentName, page: tableState.page, size: tableState.rowsPerPage, searchText: tableState.searchText}});
                                } else if(tableState.searchText === null) {
                                    phonesCollection.fetch({data: {category: this.componentName, page: tableState.page, size: tableState.rowsPerPage}});
                                }
