Bootstrap - data-toggle attribute when multiple buttons exist
===

I have several buttons and when a user clicks any button , i want to give him the expression that the button is clicked .

This is the code 

    <button class="btn btn-danger" >Today</button>
    <button class="btn btn-danger" >Tomorrow</button>
    <button class="btn btn-danger" >DayAfterTomorrow</button>

And this works when i have a single button ,

    <button class="btn" data-toggle="button">Today</button>

If the user clicks on tomorrow , still the data-toggle attribute remains for the today button.

How can i solve this?
