Pbolos,
You should use this code in the JS event handler on event you need.
For example if need to delete selection on any footer button click you should to do:
1 Activate your mobileFooter. http://prntscr.com/3j1ppx/direct
2 Open Events bottom panel and set JS event handler for "click" event. http://prntscr.com/3j1q7s/direct
3 Populate it with following code:
precode
var navBar = this;
var onDelay = function(){
jQuery(navBar).find(".ui-btn-active").removeClass("ui-btn-active");
};
window.setTimeout(onDelay, 500);
/code/pre
This will delete selection after 0.5sec after clicked on.
Regards.
