As stated by @Andreas, Number.isNumber is part of ES6 so not supported by IE11

You can add the following polyfill to you javasript

Number.isInteger = Number.isInteger || function(value) {
    return typeof value === "number" && 
           isFinite(value) && 
           Math.floor(value) === value;
};
