Hi Ajay,
If you want both filters to work, then try this -
this.getView().byId("list").getBinding("items").filter(new sap.ui.model.Filter(filters, true));
If you use false, the 'or' conjunction will be applied. If it is true then 'and' conjunction will be applied.
Check the API for more info: JsDoc Report - SAP UI development Toolkit for HTML5 - API Reference - sap.ui.model.Filter

Sai Vellanki.
