Hi can anyone tell me how i can inherit the js document signable is there in
enterprise/sign/static/src/js/common/document_signable
becasuse I want to modify the function 
registerCreatedSignItemEvents
with this
registerCreatedSignItemEvents = function ($signatureItem, type, isSignItemEditable) { if (type.name === _t("Date")) { $signatureItem.on("focus", (e) => this.fillTextSignItem( $(e.currentTarget), moment().format(time.getLangDateFormat()) ) ); } if (type.item_type === "signature" || type.item_type === "initial") { $signatureItem.on( "click", (e) => { // when signing for the first time in edit mode, clicking in .o_sign_item_display should cause the sign. // (because both edit and sign are possible) However if you want to change the signature after another // one is set, .o_sign_item_display is not there anymore. if ( this.isDialogOpen || isSignItemEditable && $(e.currentTarget).find('.o_sign_item_display').length && !$(e.target).hasClass('o_sign_item_display') ) { return; } this.handleSignatureDialogClick($(e.currentTarget), type) } ); } if (type.item_type === "sequential") { $signatureItem.on("focus", (e) => { $signatureItem.val('dsadasd') // getSequentialNumberForElementType(type.name) // .then(data => { // const numberFormatted = String(data.sequentialNumber).padStart(data.padding, '0'); // var sequentialNumberComplete // if (typeof data.prefix === 'string' && typeof data.suffix === 'string') { // sequentialNumberComplete = `${data.prefix}${numberFormatted}${data.suffix}`; // } // if (typeof data.prefix === 'string') { // sequentialNumberComplete = `${data.prefix}${numberFormatted}`; // } else if(typeof data.suffix === 'string') { // sequentialNumberComplete = `${numberFormatted}${data.suffix}`; // } // $signatureItem.val(sequentialNumberComplete); // }); }); }
if (type.auto_value && ['text', 'textarea'].includes(type.item_type)) { $signatureItem.on("focus", (e) => this.fillTextSignItem($signatureItem, type.auto_value) ); } if ( config.device.isMobile && ["text", "textarea"].includes(type.item_type) ) { const inputBottomSheet = new InputBottomSheet(this, { type: type.item_type, value: $signatureItem.val(), label: `${type.tip}: ${type.placeholder}`, placeholder: $signatureItem.attr("placeholder"), onTextChange: (value) => { $signatureItem.val(value); }, onValidate: (value) => { $signatureItem.val(value); $signatureItem.trigger("input"); inputBottomSheet.hide(); this.signatureItemNav.goToNextSignItem(); }, }); inputBottomSheet.appendTo(document.body); $signatureItem.on("focus", () => { inputBottomSheet.updateInputText($signatureItem.val()); inputBottomSheet.show(); }); } $signatureItem.on("input", (e) => { this.checkSignItemsCompletion(this.role); this.signatureItemNav.setTip(_t("next")); }); };

but i dont undestand how to inherit and access to that function
