Rauaq Arlin - Code Refactor

[FeXd]

• refactored the code that was adding and removing idt-btn-container
• previously, there was a y variable being used that was a bit confusing
• by taking an approach of de-activating all other buttons first, then adding "dt-btn-container the code is a bit more readable
• we also broke out two small functions which follows the Single Responsibility Principle
• no visual changes were made, everything should look the same
