Remove 'Sort Ascending,' 'Sort Descending' Options from menu

I want to remove 'Sort Ascending,' 'Sort Descending' Options from menu on one of my column.

Where should i add following code,



grid.on('viewready', function(){

grid.getView().hmenu.getComponent('asc').hide();

grid.getView().hmenu.getComponent('desc').hide();

});



Currently i have disabled 'Sort Ascending,' 'Sort Descending' Options using "menuDisabled: true".

But i want to remove these options completely.

Please help.
