How to change the text on a button progamatically?

You can use this code for change text on a button.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript">
    $(document).ready(function(){
    $("button").click(function(){
        $(".content").text("Test");
    });
});
</script>
<h2 class="content">This is a heading</h2>
<button>Click me to hide paragraphs</button>

Thanks Xtreem. I guess the code you posted does what I need but works by a user clicking the button itself. I'm using grocery crud where I created buttons for each record in my list. When a user clicks the button I jump to a function in the controller that either needs to change the text on a danger button, or initiate a jquery function (in the view) to change the text on a danger button. The user never clicks that danger button themselves. It is just informational.
