These two lines compile to:
`this.win.bind(RESIZE, yEvents[RESIZE].bind(RESIZE, xEvents[RESIZE]));`

When it should be:
`this.win.bind(RESIZE, yEvents[RESIZE]).bind(RESIZE, xEvents[RESIZE]);`

So both `.bind` calls should be wrapped with parentheses like this: `.bind(RESIZE, yEvents[RESIZE])`
