How to set icons based on a condition in sap.m.column : var col5 = new sap.m.Column("col5",
		  			{
		  			width:"auto", 
		  			header: new sap.m.Label({text:"Late"}),
		  			footer: new sap.ui.core.Icon({
		  		        src : {
		  		            path: "Late",
		  		            formatter: function(approved){
		  		                if (approved == "Yes")
		  		                {return "sap-icon://notification";}
		  		                else{
		  		                	
		  		                };
		  		            }
		  		        }
		  		    }),
In debug mode, I checked the value in "approved".. but it has null value. Please suggest.
