How do I Import and run 2 scripts in SS 2.x?

Question

I have a suitescript that imports 2 scripts. When the user presses a button it is supposed to run the first script and then the 2nd script. My issue is that only the function for the 1st script is running. The 2nd script is not and I see no errors in console. What am I missing?

/**
 *@NApiVersion 2.1
 *@NScriptType ClientScript
 */

define(['N/ui/dialog', './stdRates.js', './specialRates.js'], (dialog, stdRates, specialRates) => {

    function pageInit(context) {}

    function selectRateType(context) {
        const options = {
            title: 'Select Rate Types',
            message: 'Select the type of rates you want to import.',
            buttons: [{
                    label: 'To Client',
                    value: 1
                },

                {
                    label: 'Return',
                    value: 2
                }

            ]
        };

        function success(result) {

            stdRates.stdRates();
            specialRates.specialRates();
}

        function failure(reason) {
            console.log(`Failure: ${reason}`)
        }

        dialog.create(options).then(success).catch(failure);
    }

    return {
        selectRateType,
        pageInit
    };
});
