Having trouble getting Angular Filter to work within a directive expression?

I am currently working on a directive where I need to convert both the attribute and object name values to lowercase. I have tried using filters, as well as the $filter service, but it doesn't seem to be working. Can anyone please provide assistance in achieving this?

Thank you in advance.

Directive Code:

 bosAppModule.directive('layoutTableCellControlControlRender',['$compile','$filter', function($compile,$filter){
    var layoutTableCellControlRenderObj={};
    linkFnTableCellControlRender=function(scope, element, attributes) {
        scope.controlData="NOCONTROLDATA";
        scope.kendoOptions={};   
        //scope.field = $filter('lowercase')(scope.field);
    };  
    layoutTableCellControlRenderObj.scope={field:"@",tranobj:"@" };
    layoutTableCellControlRenderObj.restrict='AE';
    layoutTableCellControlRenderObj.replace='true';
    layoutTableCellControlRenderObj.template="<div field={{tablecellcontrol.attributename | lowercase }} tranobj={{tablecellcontrol.objectname | lowercase}}>" +
                                            "</div>";
    layoutTableCellControlRenderObj.link = linkFnTableCellControlRender;

    return layoutTableCellControlRenderObj; 
}]);

For a detailed explanation on the variance between '@' and '=' in directive scope in AngularJS, refer to this informative post: What is the difference between '@' and '=' in directive scope in AngularJS?

If you wish to implement Two-way model binding, it is recommended to utilize '=' for defining scope properties as shown in the snippet below:

layoutTableCellControlRenderObj.scope={field:"=",tranobj:"=" };
