I have encountered some problems with trigger(<event>) method in aspx page

the jQuery code sample is below:

jQuery(document).ready( function ( e )

{

...

$('.googlesearch').bind('keydown', function ( e ) {

if ( e.which == 13 )

{

$('.googlesubmit').trigger('click');

}

})

...

})

and the aspx code sample is like this:

<asp:textbox ID="inputSearch" runat="server" AccessKey="4" OnTextChanged="SearchText_TextChanged" CssClass="quicksearchinput googlesearch" ToolTip='<%#Translate("/templates/search/quicksearch")%>' />

<asp:LinkButton runat="server" ID="QuickSearchButton" OnClick="QuickSearchButton_Click" CausesValidation="False" CssClass="submit button">

<input type="button" class="submit button googlesubmit" value="<%=Translate("/templates/search/quicksearch")%>" onclick="parentElement.click()"/>

</asp:LinkButton>

This works on ie7/8, Google Chrome but with FF3.5 the trigger doesn't seem to actually trigger click event.

I have tested this by adding alerts before $('.googlesubmit').trigger('click') , which does show and adding $('googlesubmit').click( function (e )

{

alert('foo')

}), which doesn't work ( neither, obviously, works the intended action )
