can we call parent method from child component in vuejs

 we have two components

one is child componet and another one is pareant component

fetch is parent component 

another moderation .vue - its child

we import alert componet so its child

<submit-component

ref="submitComponent"

:max_submit_queue_count="max_submit_queue_count"

:direct_submit="direct_submit"

:multi_level_submit="multi_level_submit"

@onSubmit="afterSubmit()"

@onAlert="onAlert($event)"

@onSubmittedCount = SubmittedCount($event)

></submit-component>

v-on -> onsubmit event

afterSubmit(){

this.$refs.fetchComponent.autoFetch();

this.$refs.editorComponent.reload();

this.$refs.editorComponent.showThumbnailsTab();

},

fetchcomponent.vuie

autoFetch(){

if(!this.fetching && this.auto_fetch && this.my_queue_count < this.max_auto_fetch){

this.fetchAssignments(this.getRouteParams('level'));

this.createAssignmment(1);

}

},
