            launch: function() {
                var that = this;
                var minDate = new Date(new Date() - 8640000000*90); //milliseconds in day = 86400000   
                var datePicker = Ext.create('Ext.panel.Panel', {
                    title: 'Choose a PSI Dates',
                    bodyPadding: 10,

                            that._startDate = Ext.getCmp('start_date').getValue();
                        }
                    },
                    {

                this.add(datePicker);   
                //this.add(enddatePicker);

Use datefield instead of datepicker. JSFiddle

  items: [{
           fieldLabel: 'Start Date',
           xtype: 'datefield',              
           minDate: minDate,
           id: 'start_date',
           listeners: {
               render: function(){
                    var picker = this.getPicker();
                    picker.on("select",function(){ this.hide(); });
                    this.triggerCell.hide();
                    this.inputCell.on("click",function(){                                                  
                        if(picker.hidden)                               
                            picker.show(); 
                        else
                            picker.hide();
                     });                                    
                }
            }
        }, {
           fieldLabel: 'End Date',
           xtype: 'datefield',
           minDate: new Date(),
            listeners: {
                render: function(){
                    var picker = this.getPicker();
                    picker.on("select",function(){ this.hide(); });
                    this.triggerCell.hide();
                    this.inputCell.on("click",function(){                                                   
                        if(picker.hidden)                              
                            picker.show(); 
                        else
                            picker.hide();                            
                    });                                    
                }
            }
    }]
