Click to Increment using Java Script

I have managed to solve many technical challenges with PHPR, but I cannot solve this one:

The scenario (On an Ipad):

1. All records are in inline edit mode. (No problem)
   
2. a) I need to be able to increase a field value by selecting (clicking on) the field or a field in this record.
   
   (I can accomplish this with ONE record in inline edit mode)
   
   <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=17145&image=1&table=forumtopics' class='bbc_emoticon' alt='B)' /> If a) is not possible, I need a separate widget that opens up, with up/down arrows to increment/decrement a
   
   counter, and put this value into the applicable field in the record.
   Please note that I need to be able to do this action with minimum clicks, and HAVE TO put all records in edit mode
   
   to accomplish this.
