Adding Filter then button was not working in iOS devices

[naveenbskn]

I am having a sortable List in each li I'm having div, inside each div I'm have buttons and icons. I added the filter for that button and icon ID's, so that I can't able to drag by those. When in iOS devices when I added filter that button was not clicking on the first click itself, i need to click for 4 or 5 times to execute that functionality. so how can I solve this issue
