i want use function removeall() of stores in controller, delete content of store in view.is possible? here code:

my view:

ext.define('demoapp.view.mainmenu',{ extend:'ext.form.panel', requires:['ext.titlebar','demoapp.store.ccaa'], alias:'widget.mainmenuview', config:{     layout:{         type:'fit'     },     items:[{         xtype:'fieldset',         items:[{             xtype:'titlebar',             title:'menú principal',             docked:'top',             items:[{                 xtype:'button',                 text:'desconectar',                 itemid:'logoffbutton',                 align:'right'             }]         },         {             xtype:'fieldset',             items:[{                 xtype:'selectfield',                 itemid:'ccaacombo',                 label:'comunidad autonoma',                 store:'storeccaa',                 displayfield:'nombre',                 valuefield:'id',                 autoselect:false,                 placeholder:'elige una para filtrar'             }]         }         ]     }],     listeners:[{         delegate:'#logoffbutton',         event:'tap',         fn:'onlogoffbuttontap'     },     {         delegate:'#ccaacombo',         event:'change',         fn:'onccaacombochange'     }] }, onlogoffbuttontap:function(){     this.fireevent('onsignoffcommand'); }, onccaacombochange:function(field,value){     console.log("estoy en la vista");     var idccaa=value;     console.log(idccaa);     this.fireevent('onccaacombochangeaction',idccaa); } }); 

my controller:

ext.define('demoapp.controller.mainmenu',{ extend:'ext.app.controller', config:{     refs:{         loginview:'loginview',         mainmenuview:'mainmenuview'     },     control:{         mainmenuview:{             onsignoffcommand:'onsignoffcommand',             onccaacombochangeaction:'onccaacombochangeaction'         }     } },  //transicion getsliderighttransition: function () {     return { type: 'slide', direction: 'right' }; },  //funciones onsignoffcommand:function(){     var me=this;      ext.viewport.animateactiveitem(this.getloginview(),this.getsliderighttransition());  }, onccaacombochangeaction:function(idccaa){     console.log("estoy en el controlador");     console.log(idccaa); } }); 

in controller,after line var me=this in onsignoffcommand:function() want use removeall() function of store:'storeccaa' of view.

add refs selectfield in controller

ext.define('demoapp.controller.mainmenu',{     extend:'ext.app.controller',     config:{         refs:{             loginview:'loginview',             mainmenuview:'mainmenuview',             mainmenuviewselectfield: 'mainmenuview selectfield#ccaacombo'         },         control:{             mainmenuview:{                 onsignoffcommand:'onsignoffcommand',                 onccaacombochangeaction:'onccaacombochangeaction'             }         }     },      //transicion     getsliderighttransition: function () {         return { type: 'slide', direction: 'right' };     },      //funciones     onsignoffcommand:function(){         var me=this;          // store of select field , remove records         this.getmainmenuviewselectfield().getstore().removeall();         ext.viewport.animateactiveitem(this.getloginview(),this.getsliderighttransition());      },     onccaacombochangeaction:function(idccaa){         console.log("estoy en el controlador");         console.log(idccaa);     } });
