                            <div ng-switch-when="ms-select-single" >
                                <div ms-select-single quest='quest'
                                 quest-num='{{(true)?numInc():return}}'></div>
                            </div>
                            <div ng-switch-when="ms-select-multy">
                                <div ms-select-multy quest='quest'
                                quest-num='{{(true)?numInc():return}}'></div>
                            </div>
                            <div ng-switch-when="ms-date">
                                <div ms-date quest='quest'
                                 quest-num='{{(true)?numInc():return}}'>{{questNo}}</div>
                            </div>
                            <div ng-switch-when="ms-text">
                                <div ms-text quest='quest'
                                quest-num='{{(true)?numInc():return}}'>{{questNo}}</div>
                            </div>
                            <div ng-switch-when="ms-textarea">
                                <div ms-textarea quest='quest'
                                quest-num='{{(true)?numInc():return}}'>{{questNo}}</div>
                            </div>
                            <div ng-switch-when="ms-number">
                                <div ms-number quest='quest'
                                quest-num='{{(true)?numInc():return}}'>{{questNo}}</div>

                            <div ng-switch-when="ms-html">
                                <div ms-html quest='quest'></div>
                            </div>
