[TIMOB-9718] MobileWeb: textField events generate bad behaviors

Problem description

Setting event listeners (tested using 'blur', 'focus' and 'change') to a textField results in getting bad behaviors, depending on the browser (tested on Firefox and Safari)

Steps to reproduce

Run sample code and click on the textField. Result: Firefox: blur and focus events are triggered, then textField it's not focused. Safari: blur and focus events are triggered continuously (then have to actually kill the browser in this case)

var  win = Titanium.UI.createWindow({
                    backgroundColor:'#000'
                });
 
var inputTextField = Titanium.UI.createTextField({
        color : '#ff7c00',
        top:10,
        height : 50,
        width : '25%',
        left : '10%',
        borderStyle : Titanium.UI.INPUT_BORDERSTYLE_ROUNDED,
        keyboardType : Titanium.UI.KEYBOARD_NUMBERS_PUNCTUATION,
        returnKeyType : Titanium.UI.RETURNKEY_DONE,
        font : {
            fontSize : 20,
            fontColor : '#ff7c00',
            fontWeight : 'bold',
            fontFamily : 'Helvetica Neue'
        }
    });
inputTextField.addEventListener('focus',function(){
    alert('focus');
    Ti.API.info('focus');
});
inputTextField.addEventListener('blur',function(){
    alert('blur');
    Ti.API.info('blur');
});
inputTextField.addEventListener('change',function(){
   alert('change');
   Ti.API.info('change');
});

win.add(inputTextField);
win.open();

Additional Notes:

Set only one single event to be triggered. Result: only the 'focus' event it's not behaving correctly: Firefox: focus event triggered, textField it's not being focused. Other events work fine. Safari: focus event triggered continuously. Other events work fine. However, there are issues when setting 'blur' and 'change' events together: Firefox: typing a character, also the blur event it's triggered (should be triggered only the change one) Safari: typing a character, the blur event it's triggered continuously (have to kill the browser in this case too)
