Trouble with add Filters Programatically

Hi

I am trying to add filters programmatically and want to add Number filter and using the following code.

grid.filters.store.addFilter({ operator: 'gt', property: name, value: value });

grid.filters.store.addFilter({ operator: 'lt', property: name, value: nvalue });

it only adds for lt not the gt one. Any help/guidance.
