Angular - Call parent method from child modal created by service -


i have parent component displaying list of records in table. each record has button can click , calls method called newversioncheck(), seen below.

// creates new version target createnewversion(){     alert('create new version flow'); }  /**  * if draft exists, prompt user load , modify existing  * or discard , create new draft. if no draft exists,  * use createnewversion flow  *   * @param {any} ruleid   * @memberof versionscomponent  */ newversioncheck() {      let versionhasdraft = false;      // check see if target has draft.     // if dont, take them new version flow     if (!_.find(this.mapversionsdata, { isdraft: '1' })) {         this.createnewversion();     }else{          // our draft version object         let versionobj = _.find(this.mapversionsdata, { isdraft: '1' });          // tell our subject data sending modal         this._mapsservice.updateconfirmexistingversionmodaldata({             targetid: this.targetid,             createdbyqid: this.qid,             clonerules: 1,             versionobj: versionobj,         });          // call our modal, pass confirmexistingversionmodalcomponent         this.bsmodalref = this.modalservice.show(confirmexistingversionmodalcomponent);      }         }

this opens modal component , pass data display in body.

my problem here modal, want able call createnewversion() upon button click in parent component.

normally, use eventemitter @output , pass data child. however, since modal called service, don't know how go doing that.

i tried adding parent constructor of modal got circular dependency error.

how can call method modal?
