I'm simply too stupid for that. Why does the following not work?
Debugging the lines there the function is called without any error.
<button class="k-button" id="myTextButton" type="button">Enable</button>
....
<script>
$(document).ready(function () {
$("#myTextButton").click(function () {
("#myTextButton").enable(true);
("#myTextButton").value = "value text";
("#myTextButton").text = "text text";
("#myTextButton").html = "html text";
("#myTextButton").innerHTML = "innerHTML text";
});
</script>
