Formatter and table data display in the SAPUI5

JSON data:

    var data1 = {
                "results": [
                    {"option": "Quality Certificate 1", "Selected": "0"},
                    {"option": "Quality Certificate 2", "Selected": "1"}
                ]< c5/>};
    var Omodel = new Sap.ui.model.json.JSONModel (data1);
    This.getview (). Setmodel (Omodel);

XML View display:

<table id= "_table1" items= "{path: '/results '}" visible= "true" inset= "false" >
     <columns>
        < column>
        </Column>
    </columns>

    <items>

        <ColumnListItem>
            < cells>
                <radiobutton groupname= "option" text= "{option}" selected= "{path: ' selected ', Formatter: '. Checkselectedoption '} '/>
            </cells>
        </ColumnListItem>
    </items>  
</ Table>

Whether to select the formatter code:

Checkselectedoption:function (value) {
    if (value = = "1") 
        return true;
    else
        return false;
},
