Double click needed in firefox

Double click needed in firefox


I have a list with links, once i click a link i load an external html file inside the  the content div, called leftColum. This works great on IE but i need to double click on firefox for the html to be loaded! any ideas?

    function replaceContent( buttonId, content ){
       
        $(document).ready(function(){
            $(buttonId).click(function(){
            $("#leftColumn").load(content);
        })
        });
        return false;
    }
//more code
//i call the function here
<li><a id="link1" href="#" onclick="return replaceContent('#link1','content.html');">First Link</a></li>
