my ipad home button is not working and the touch in my screen isnt working either how do i fix it ?

If your iPod Touch, iPhone, or iPad is Broken

Apple does not usually fix iDevices except for screens and minor work they can do in their shop. Instead, they exchange yours for a refurbished or new replacement depending on the age of your device and refurbished inventories. On rare occasions when there are no longer refurbished units for your older model, they may replace it with the next newer model. You may take your device to an Apple retailer for help or you may call Customer Service and arrange to send your device to Apple: You can make an appointment at the Apple Retail Store - Genius Bar and take it in for service. You can also look for an Apple Store - Find a Store - Apple. You will find respective repair costs in the appropriate link:

If it just stopped responding in an app you need to do a hard reset.

To hard reset, hold the Sleep/Wake and home buttons until the Apple logo appears on the screen.
