How to hide the NULL values in list item get from store in sencha touch

Question

I have implemented an application in sencha touch.

in that i have a list view , i retrieve the data from the store,

in data base in some fields i have inserted null values,{No selection}.

the corresponding fields in list view are displayed as NULL,

But i want to display an empty space instead of NULL,

        {
                  xtype: 'list',

                  itemTpl: [
                            '<div id="wrapper">'+
                            '<div class="frt">{Name}</div>'+
                            '<div class="frt">{Title}</div>'+
                            '<div class="frt">{Contact}</div>'+
                            '<div class="frt">{Zip}</div>'+
                            '</div>'
                            ],
