jqxDateTimeInput - (month-only input) Padding on buttons not applied initially

[Svetoslavb04]

Describe the bug The date time input is set to month-only input (views:["year", "decade"]). When you pick a month for the first time the buttons dont have padding. After the initial selection, the buttons style is applied and they have padding.

To Reproduce Steps to reproduce the behaviour:

1. Go to https://jsfiddle.net/Svetoslavb/4nmx8a69/1/
2. Click on the input
3. See an error
4. Click on the input again
5. See the applied padding

Expected behaviour The padding should be applied initially
