Popover Does Not Display When Opened

I did some digging in the ionic CSS for popover, and the opacity is set to 0 by default. You can override the opacity to 1 and the popover will display, but I found this: https://github.com/driftyco/ionic/issues/2343. Basically, you have to pass the event ($event) to popover.show() and it will work. The ionic example shows this but the documentation could be more explicit. In your code, change your template to ng-click="searchResults.openPopover($event)".
