Jquery replace input button onclick event

I have HTML loaded with the Jquery .load method and need to dynamically change anchor HREF and input but开发者_开发问答ton ONCLICK targets in this HTML on the client as the page loads, (I don't have the option to change the server generated HTML).

The .load works fine and I can change the HREF target OK but I can't find a way of changing the ONCLICK target?

HTML

1. Anchor HREF

   <div style="width:143px;" id="LM_OBJV">
   <span title="View Objectives Detail" class="PSHYPERLINK">
   <a class="PSHYPERLINK" href="javascript:Action_win0
   (document.win0,'LM_OBJV','Relationship Building',false,true);" tabindex="54"
   id="LM_OBJV" name="LM_OBJV">Relationship Building</a>
   </span>
   </div>
   

2. Button ONCLICK

   <div id="win0divLM">
   <a id="Left" style="background-Color: transparent;border:0;" class="PBUTTON">
   <span style="background-Color: transparent;">
   <input type="button" onclick="Action_win0(document.win0,'LM_PB', 0, 0, 'Add New',
     false, true);" style="width:120px; " class="PBUTTON" value="Add New" tabindex="77" 
   id="LM_PB" name="LM_PB">
   </span>
   </a>
   </div>
   

Javascript

$('#result').load('some.php', function() {

    $("a.PSHYPERLINK")
    .each(function()
    { 
        this.href = this.href.replace("Action_win0", "Action_winx");

    });

});

So this JS works fine, loads the HTML into the #results DIV and changes the HREF's from "Action_win0" to "Action_winx".

But how can I also change the input type="button ONCLICK events from "Action_win0" to "Action_winx"? I've tried several Jquery selectors but just can't get it to work :(

$('a.PSHYPERLINK').attr('onclick', 'alert("bar")')
