Unable to click on button using Appium Android

Unable to click on button using Appium Android
Our application shows up an alert Dialog which gives use to accept or cancel button. This alert is designed as a view.
I’m able to identify the button but click action is not happening. No server side exceptions are thrown
Any help on this issue is highly appreciated.

Note: As a work around used adb command to click and it works and the application is built on Ionic framework

OS : Windows
Appium library : C#
Appium server 1.2.4.1
