Unable to edit input field with JQuery editable plugin after setting default value

Question

I am trying to clone a row in a table and want to set default values for some td elements for editing. If I don't set default value, I am able to edit that td div element but if I set default value I am unable to edit.

Here is the code:(if I remove html("") I am able to edit td div elements)

 $("#create_blank_scenario").click(function(){
                var row = $('#sortable_offer_table tbody tr:first').clone(true);

                row.find("td div").editable( { onEdit:selectText}).addClass("editable").html("");               

                row.insertBefore('#sortable_offer_table tbody tr:first');

              });

Code for selectText:

function selectText(content){
    this.children("input").select();

}

editable css:

.editable input{
font-size:10px; 
width:40px;
border:0;

}
