jQuery in admin panel not triggering function

I’ve been struggling for some time with this … I just can’t seem to get functions to be triggered from within the admin panel for a plugin I’m writing! I’ve pared it down to this …

My HTML code is:

<p>
  <label for="psw_upload_image">
  <input id="psw_upload_image" type="text" size="36" name="psw_upload_image" value="" />
  <input id="psw_upload_image_button" type="button" value="Upload Image" />
  <br />Enter an URL or upload an image for the banner.
  </label>
</p>

The scripts are in the pluginn’s functions file as follows:

function psw_admin_scripts() {
	wp_enqueue_script('media-upload');
	wp_enqueue_script('thickbox');
	wp_register_script('psw-upload', WP_PLUGIN_URL.'/psw-base/code/psw-script.js', array('jquery','media-upload','thickbox'));
	wp_enqueue_script('psw-upload');
}

function psw_admin_styles() {
	wp_enqueue_style('thickbox');
}

add_action('admin_print_scripts', 'psw_admin_scripts');
add_action('admin_print_styles', 'psw_admin_styles');

The JavaScript file mentioned above contains the following (just debug code at the moment until I can figure out why this isn’t working!):

jQuery(document).ready
	(function()
		{
		alert('A');
		jQuery('#psw_upload_image_button').click
				(function()
					{
					alert("Hello");
					}
				);
		alert('B');
		}
	);

I’ve used firebug to put breakpoints into the code above, and everything gets called correctly when the page loads, but, when I click the button, nothing happens (obviously I’m expecting a box with “Hello!” to appear.

The two boxes with “A” and “B” appear OK when the page is loaded, just not my “Hello!” box :(.

Help!
