Try this on your button click inside your application
String appPackage = getPackageName(); 
try {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackage)));
} catch (android.content.ActivityNotFoundException ex) {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + appPackage)));
}

Edit 1: 
I found some sample for opening twitter app from iconic android. Similarly you can try for google app store
var scheme;
if(device.platform === 'iOS') {
    scheme = 'twitter://';
}
else if(device.platform === 'Android') {
    scheme = 'com.twitter.android';
}
appAvailability.check(
    scheme, // URI Scheme
    function() {  // Success callback
        window.open('twitter://user?screen_name=gajotres', '_system', 'location=no');
        console.log('Twitter is available');
    },
    function() {  // Error callback
        window.open('https://twitter.com/gajotres', '_system', 'location=no');
        console.log('Twitter is not available');
    }
);
