AEM6.3 coral touch ui bypass required image using javascript

Hi ,

i have fileupload marked as mandatory for image field but since i am doing some java-script manipulation, hence  I need to bypass this and still submit the dialog even if the image is empty.

Please let me know how this can be achieved.

<image

                                        jcr:primaryType="nt:unstructured"

                                        sling:resourceType="cq/gui/components/authoring/dialog/fileupload"

                                        autoStart="{Boolean}false"

                                        class="cq-droptarget"

                                        fieldDescription="The  Image ."

                                        fieldLabel=" Image"

                                        fileNameParameter="./image/fileName"

                                        fileReferenceParameter="./image/fileReference"

                                        mimeTypes="[image]"

                                        multiple="{Boolean}false"

                                        name="./Image"

                                        required="{Boolean}true"

                                        title="Upload Image Asset"

                                        uploadUrl="${suffix.path}"

                                        useHTML5="{Boolean}true"/>

Thanks
