Description

Problem description

tableView 'scroll' event is triggered also when just opening the tableView, clicking on a row or opening the keyboard.

Steps to reproduce

- Create a tableView and set an event listener associated to the 'scroll' event Result: function is called when opening the window, clicking on a row in the tableView and other events not relative to scroll (see code sample - also when clicking on a textField and opening the keyboard) Same code works as expected on iOS.

var win = Ti.UI.createWindow({
	title:'pippo',
	backgroundColor:'gray'
});

var search = Titanium.UI.createTextField({ 
	// color:'#336699', 
	top:5,
	width:400,
	left:10, 
	hintText:'Search for ...',
	borderStyle:Titanium.UI.INPUT_BORDERSTYLE_ROUNDED, keyboardType:Titanium.UI.KEYBOARD_DEFAULT, returnKeyType:Titanium.UI.RETURNKEY_DEFAULT
});

win.add(search);

var data = [];
var autocomplete_table = Titanium.UI.createTableView({ 
	scrollable: true, 
	top: 170,
	bottom:0,
	backgroundColor:'white',
	data:data
});

var row = Ti.UI.createTableViewRow({
	title:'test'
});
data.push(row);

var autocomplete_table = Titanium.UI.createTableView({ 
	scrollable: true, 
	top: 170,
	bottom:0,
	backgroundColor:'white',
	data:data
});


win.add(autocomplete_table);

autocomplete_table.addEventListener('scroll', function(e) { 
	search.blur(); 
	alert('triggered!')
});

win.open();

       backgroundColor:'gray'
   });
    
   var search = Titanium.UI.createTextField({

       top: 170,
       bottom:0,
       backgroundColor:'white',
       data:data
   });
   
   for (i=0;i<50;i++)
   { 
   	var row = Ti.UI.createTableViewRow({
       	title:'test' + i
   	});
   	data.push(row);
   }
    
   var autocomplete_table = Titanium.UI.createTableView({ 
       scrollable: true, 
       top: 170,
       bottom:0,
       backgroundColor:'white',
