My touch screen not working

@faheemabrahams anytime you have a cracked screen, it is possible that this expands internally by continues use until it finally damages the grid for the touchscreen. I suggest that you replace the screen and then re-evaluate.

Since iFixit does not yet have a specific guide for that use something like this video Remember there are two ways to replace the LCD. One is to just replace the LCD and the other way is to replace it with the frame. Get an LCD with the frame. It will be slightly more expensive but it will be a much safer and quicker way to replace it. You will not need to use heat and to remove the screen from the frame, which may lead to further damage.

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same issues with their device. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
