fix(android): append ListView events while scrolling

[m1ga]

Before this PR the template events only worked for visible items. Items that were generated during scrolling didn't have the events.

Test

var win = Ti.UI.createWindow({
    backgroundColor: 'white'
});

function playout() {
    console.log("Post")
    this.removeEventListener("postlayout", playout);
    this.animate({
        opacity: 1,
        duration: 150,
        curve: Titanium.UI.ANIMATION_CURVE_EASE_IN
    });
}

var myTemplate = {
    events: {
        postlayout: playout
    },
    properties: {
        height: 100,
        opacity: 0.1
    },
    childTemplates: [{
            type: 'Ti.UI.Label',
            bindId: 'info',
            properties: {
                color: 'black',
                font: {
                    fontFamily: 'Arial',
                    fontSize: '20dp',
                    fontWeight: 'bold'
                },
                left: '60dp',
                top: 0,
            }
        },
        {
            type: 'Ti.UI.Label',
            bindId: 'es_info',
            properties: {
                color: 'gray',
                font: {
                    fontFamily: 'Arial',
                    fontSize: '14dp'
                },
                left: '60dp',
                top: '25dp',
            }
        }
    ]
};

    templates: {
        'template': myTemplate
    },

• run the code
• scroll and see if the elements fade in
