I notice that you’re binding click events to elements other than buttons or <a> tags. This was my issue when I was getting the 300ms delay. Apparently there is code in ionic that addresses the 300ms delay issue, but only for these two elements. See this posting for a little more detail. I had been using divs for click events and getting the delay. I changed the divs to <a> elements and the 300ms delay was resolved for my app. FYI.
