javascript document.ready not running

[nosfa]

Hi.

In my MVC project I have a button that has to trigger a script.
As it happens the page doesn't listen to the event.

I put the script in my view where the form is.

this works

<script >
              alert("it worked");
</script>

this doesn't work

<script >
         $(document).ready(function () {
            $("#btnSubmit").click(function () {
                alert("it worked");
</script>

this doesn't work

<script >
             $(window).load(function () {
                $("#btnSubmit").click(function () {
                    alert("it worked");
    </script>

Can't find any solution on the net

Thanks in advance
