I am facing a problem related i think to event management and 300 ms delay between end tap action and real click event

My scenario

I write a on-tap handler and inside this handler i retrieve a value of an input field display in the page (but the value of the field is process and transform by the on change event of the field itself).

My big problem is the delay between execution of the  change event and tap event 

During execution of tap handler , the change event are not still triggered . And i need something done during the on change handler .

If inside my tap handler , i put my code which need the work of change handler , inside a timeout (> 350 ms) magically it's works fine 

My application is a cordova web application and run on a Android device (4.4.2) 

I hope you can help me to find a solution
